Subject: [PATCH v4 0/2] Add support for Broadcom iProc touchscreen

This patchset contains initial support for the touchscreen on the Broadcom
iProc family of SoCs. This driver has been validated with Cygnus and is expected
to work on other iProc family of SoCs that use the same touchscreen controller.

Changes from v3:
- Fixed typo in Kconfig.

Changes from v2:
- Misc style changes.
- Removed assumptions about interrupts generated in ISR. It now emits all
  events and then syncs if necessary.
- Removed our rotation property and replaced with the latest
  touchscreen-inverted-x/y. Also added support for the standard optional
  properties touchscreen-size-x/y and touchscreen-fuzz-x/y. Did not add support
  for inverted-x/y at this time as our touchscreen is currently only oriented
  180 degres.

Changes from v1:
- Add missing newlines to debug messages
- Use BIT macro for defines
- Fix logic in get_tsc_config to improve readability
- Get rid of unnecessary remove() function
