The Kconfig and file naming for the PM8xxx driver is totally
confusing:

- Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel
  users depending on or selecting either at random.
- A driver file named pm8921-core.c even if it is indeed
  used by the whole PM8xxx family of chips.
- An irqchip named pm8xxx since it was (I guess) realized that
  the driver was generic for all pm8xxx PMICs.

As I may want to add support for PM8901 this is starting to get
really messy. Fix this situation by:

- Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX
  and convert all users, including LEDs Kconfig and ARM defconfigs
  for qcom and multi_v7 to use that single symbol.
- Renaming the driver to qcom-pm8xxx.c to fit along the two
  other qcom* prefixed drivers.
- Rename functions withing the driver from 8921 to 8xxx to
  indicate it is generic.
- Just drop the =m config from the pxa_defconfig, I have no clue
  why it is even there, it is not a Qualcomm platform. (Possibly
  older Kconfig noise from saveconfig.)

The driver is for a trackpad device so is not needed for booting and
makes more sense to have it as module to reduce the kernel image size.

It was probably enabled as built-in because module autoload was not
working when the I2C device was registered by OF but this got fixed
in commit b7d21058 ("Input: atmel_mxt_ts - add maxtouch to I2C
table for module autoload") so it's safe to enable as a module now.

drivers/input/built-in.o:(.debug_addr+0x34): undefined reference to `input_set_capability'

This removes the 'select' as suggested by Krzysztof Kozlowski and
instead enables the driver from the defconfig files.

The problem does not happen on mainline kernels, as we don't normally
build built-in input drivers when CONFIG_INPUT=m, but I am experimenting
with a patch to change this, and the samsung keypad driver showed up
as one example that was silently broken before.
