The setting of VMMCI differs so much between different
boards that we need to handle it on a per-board basis
rather that complicating things by overriding stuff from
the included DTSI:s. Push it down into top-level tree
instead.

The DB8500 exists in an enhanced variant named DB8520
for some machines. To clearly distinguish between the
different machines, create an explicit db8500.dtsi
and move the operating points (only known difference so
far) to that file, so we can add an explicit db8520.dtsi
after this.

At the moment, all 5 I2C and 6 SPI buses are probed and exposed
to user-space by default - even if they are not muxed to any pins
on the board. This means that user-space sees an I2C/SPI bus that
cannot be actually used properly.
In some cases this was used to put the corresponding pins into
a low power sleep mode - but even then the pins first need to be
configured by the board-specific device tree part.
Avoid exposing unconfigured devices to user-space by disabling
the I2C/SPI buses by default. Enable them in the board device trees
when needed.

This moves the enable-active-high setting from the SoC to the
board for the VMMCQ regulators. It should at least be in the
vicinity of the GPIO line it is defined for.

Use the <dt-bindings/gpio/gpio.h> header instead of using
hardcoded values for the GPIO flags. Eradicate the totally
bogus "0x4" flag used and set that to GPIO_ACTIVE_HIGH as is
proper, switch the inverted card detect on the Snowball to
flag using GPIO_ACTIVE_LOW instead of using the MMC-specific
inversion flag.

Ux500 is regressing due to commit
a21763a0b1
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

This converts the Nomadik pin controller and all associated device
trees to use the standard, generic config bindings for pin controllers.
There are no such device trees deployed in the wild so this is
safe to do to set a good example.

This moves the SPI pin control table out of the board file
and into the device tree. Move the specific setting for
SSP0 on the HREFprev60 into the prev60-specific DTS file.
The SPI2 configuration is not really connected to any device,
as it will conflict with GPIO218 which is used on all HREFs.

As the device tree conversion did away with the ability to
auto-detect the UIB (User Interface Board) version from attempting
to read an I2C address, we now have to pass the knowledge of
what UIB is mounted through the device tree. This gives rise
to four possible board permutations:
- HREF prior to v60, ST UIB (hrefprev60-stuib)
- HREF prior to v60, TVK1281618 UIB (hrefprev60-tvk)
- HREF v60 and later, ST UIB (href60plus-stuib)
- HREF v60 and later, TVK1281618 UIB (hrefv60plus-tvk)
