spi: pxa2xx: Provide num-cs for Sharp PDAs via device properties

Since driver can parse num-cs device property, replace platform data
with this new approach. This pursues the following objectives:

- getting rid of the public header that barely used outside of
the SPI subsystem (more specifically the SPI PXA2xx drivers)

- making a trampoline for the driver to support non-default number
of the chip select pins in case the original code is going to be
converted to Device Tree model

It's not expected to have more users in board files except this one.

ARM: 9298/1: Drop custom mdesc->handle_irq()

ARM exclusively uses GENERIC_IRQ_MULTI_HANDLER, so at some point
set_handle_irq() needs to be called to handle system-wide
interrupts.

For all DT-enabled boards, this call happens down in the
drivers/irqchip subsystem, after locating the target irqchip
driver from the device tree.

We still have a few instances of the boardfiles with machine
descriptors passing a machine-specific .handle_irq() to the
ARM kernel core.

Get rid of this by letting the few remaining machines consistently
call set_handle_irq() from the end of the .init_irq() callback
instead and diet down one member from the machine descriptor.

Input: ads7846 - Convert to use software nodes

The Nokia 770 is using GPIOs from the global numberspace on the
CBUS node to pass down to the LCD controller. This regresses when we
let the OMAP GPIO driver use dynamic GPIO base.

The Nokia 770 now has dynamic allocation of IRQ numbers, so this
needs to be fixed for it to work.

As this is the only user of LCD MIPID we can easily augment the
driver to use a GPIO descriptor instead and resolve the issue.

The platform data .shutdown() callback wasn't even used in the
code, but we encode a shutdown asserting RESET in the remove()
callback for completeness sake.

The CBUS also has the ADS7846 touchscreen attached.

Populate the devices on the Nokia 770 CBUS I2C using software
nodes instead of platform data quirks. This includes the LCD
and the ADS7846 touchscreen so the conversion just brings the LCD
along with it as software nodes is an all-or-nothing design
pattern.

The ADS7846 has some limited support for using GPIO descriptors,
let's convert it over completely to using device properties and then
fix all remaining boardfile users to provide all platform data using
software nodes.

Dump the of includes and of_match_ptr() in the ADS7846 driver as part
of the job.

Since we have to move ADS7846 over to obtaining the GPIOs it is
using exclusively from descriptors, we provide descriptor tables
for the two remaining in-kernel boardfiles using ADS7846:

- PXA Spitz
- MIPS Alchemy DB1000 development board

It was too hard for me to include software node conversion of
these two remaining users at this time: the spitz is using a
hscync callback in the platform data that would require further
GPIO descriptor conversion of the Spitz, and moving the hsync
callback down into the driver: it will just become too big of
a job, but it can be done separately.

The MIPS Alchemy DB1000 is simply something I cannot test, so take
the easier approach of just providing some GPIO descriptors in
this case as I don't want the patch to grow too intrusive.

As we see that several device trees have incorrect polarity flags
and just expect to bypass the gpiolib polarity handling, fix up
all device trees too, in a separate patch.

Looking at the recent changes, I found that commit 31455bbda208 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."

After reviewing the change I conclude that the same fix is needed
for all affected boards.
