Input: bcm5974 - set missing URB_NO_TRANSFER_DMA_MAP urb flag
Input: raspberrypi-ts - add missing HAS_IOMEM dependency
The bcm5974 driver does the allocation and dma mapping of the usb urb
data buffer, but driver does not set the URB_NO_TRANSFER_DMA_MAP flag
to let usb core know the buffer is already mapped.
usb core tries to map the already mapped buffer, causing a warning:
"xhci_hcd 0000:00:14.0: rejecting DMA map of vmalloc memory"
Fix this by setting the URB_NO_TRANSFER_DMA_MAP, letting usb core
know buffer is already mapped by bcm5974 driver

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.

Currently, when trying to suspend and resume with VirtualPS/2 VMMouse
there is an error message after resuming:
psmouse serio1: vmmouse: Unable to re-enable mouse when reconnecting, err: -6
and the mouse will no longer be operable, requiring full rescan to find a
another driver to use for the port.
This error is due to QEMU still generating PS2 events which the kernel is
not consuming until resume time, where they interfere with mouse
identification and ultimately resulting in an error getting
VMMOUSE_VERSION_ID.
Test scenario:
1) start virtual machine with qemu command "vmport=on"
2) click suspend botton to enter suspend mode
3) resume and observe the error message in the kernel logs
Let's fix this by disabling the vmmouse in its reset handler. This will
notify qemu to stop vmmouse and remove the handler.

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Before these changes elan_suspend() would only disable the regulator
when device_may_wakeup() returns false; whereas elan_resume() would
unconditionally enable it, leading to an enable count imbalance when
device_may_wakeup() returns true.
This triggers the "WARN_ON(regulator->enable_count)" in regulator_put()
when the elan_i2c driver gets unbound, this happens e.g. with the
hot-plugable dock with Elan I2C touchpad for the Asus TF103C 2-in-1.
Fix this by making the regulator_enable() call also be conditional
on device_may_wakeup() returning false.

elan_disable_power() is called conditionally on suspend, where as
elan_enable_power() is always called on resume. This leads to
an imbalance in the regulator's enable count.

When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.
This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.
So this patch moves dev->work initialization before registering input
device

With the new RMI4 F3A support, we're now able to enable full RMI4

Fix this by returning the value in retval instead of count.
