spi: dw: Put the driver entities naming in order
Mostly due to a long driver history it's methods and macro names look a
bit messy. In particularly that concerns the code their prefixes. A
biggest part of the driver functions and macros have got the dw_spi/DW_SPI
prefixes. But there are some entities which have been just
"spi_/SPI_"-prefixed. Especially that concerns the CSR and their fields
macro definitions. It makes the code harder to comprehend since such
methods and macros can be easily confused with the global SPI-subsystem
exports. In this case the only possible way to more or less quickly
distinguish one naming space from another is either by context or by the
argument type, which most of the times isn't that easy anyway. In addition
to that a new DW SSI IP-core support has been added in the framework of
commit e539f435cb ("spi: dw: Add support for DesignWare DWC_ssi"), which
introduced a new set or macro-prefixes to describe CTRLR0-specific fields
and worsen the situation. Finally there are methods with
no DW SPI driver-reference prefix at all, that make the code reading even
harder. So in order to ease the driver hacking let's bring the code naming
to a common base:
1) Each method is supposed to have "dw_spi_" prefix so to be easily
distinguished from the kernel API, e.g. SPI-subsystem methods and macros.
(Exception is the local implementation of the readl/writel methods since
being just the regspace accessors.)
2) Each generically used macro should have DW_SPI_-prefix thus being
easily comprehended as the local driver definition.
3) DW APB SSI and DW SSI specific macros should have prefixes as DW_PSSI_
and DW_HSSI_ respectively so referring to the system buses they support
(APB and AHB similarly to the DT clocks naming like pclk, hclk).

spi: dw: Add DWC SSI capability
Currently DWC SSI core is supported by means of setting up the
core-specific update_cr0() callback. It isn't suitable for multiple
reasons. First of all having exported several methods doing the same thing
but for different chips makes the code harder to maintain. Secondly the
spi-dw-core driver exports the methods, then the spi-dw-mmio driver sets
the private data callback with one of them so to be called by the core
driver again. That makes the code logic too complicated. Thirdly using
callbacks for just updating the CR0 register is problematic, since in case
if the register needed to be updated from different parts of the code,
we'd have to create another callback (for instance the SPI device-specific
parameters don't need to be calculated each time the SPI transfer is
submitted, so it's better to pre-calculate the CR0 data at the SPI-device
setup stage).

So keeping all the above in mind let's discard the update_cr0() callbacks,
define a generic and static dw_spi_update_cr0() method and create the
DW_SPI_CAP_DWC_SSI capability, which when enabled would activate the
alternative CR0 register layout.

While at it add the comments to the code path of the normal DW APB SSI
controller setup to make the dw_spi_update_cr0() method looking coherent.

spi: dw: Move Non-DMA code to the DW PCIe-SPI driver
This is a preparation patch before adding the DW DMA support into the
DW SPI MMIO driver. We need to unpin the Non-DMA-specific code from the
intended to be generic DW APB SSI DMA code. This isn't that hard,
since the most part of the spi-dw-mid.c driver in fact implements a
generic DMA interface for the DW SPI controller driver. The only Intel
MID specifics concern getting the max frequency from the MRST Clock
Control Unit and fetching the DMA controller channels from
corresponding PCIe DMA controller. Since first one is related with the
SPI interface configuration we moved it' implementation into the
DW PCIe-SPI driver module. After that former spi-dw-mid.c file
can be just renamed to be the DW SPI DMA module optionally compiled in to
the DW APB SSI core driver.

bits, but it does not mean to have power of two of this bits as a possible

There are more that one SPI controller on the Intel MID boards. This patch
describes the status and IDs of them. From now on we also have to care about
bus number that must be unique per host.

According to the specification the SPI1 has 5 bits for chip selects and SPI2
only 2 bits. The patch makes it depend to PCI ID.

The first controller (SPI1) is DMA capable, meanwhile SPI2 can share same
channels (via software switch) such functionality is not in the scope of this
patch. Thus, attempt to init DMA for SPI2 will always fail for now.

d7614de422 spi: Add module.h to implicit users in drivers/spi
We are clipping down the presence of module.h, since it was
everywhere.  If you really need it, you better call it out,
as per this changeset.

ca632f5566 spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.

This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.

v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
      be the predominant pattern for subsystem prefixes.
    - Clean up filenames in Kconfig and header comment blocks
