Abraham Arce 5ad567ffba Input: omap4-keypad - wire up runtime PM handling
Enable Runtime PM functionality in OMAP4 driver based on the following
assumptions:

- keyboard controller in wakeup domain so it is always on and power
  impact is minimal;
- in OMAP4 the device control is at module/device level and ick/fclk
  level control is difficult so cutting of clocks will prevent
  interrupts.

Mike Turquette 9a34bc6116 Input: omap4-keypad - wake-up on events & long presses
Program keyboard controller to generate a wake-up request on events and
on long key presses. It will not generate wake-up requests on timeouts
since driver code does not handle them.

This allows keyboard to wake-up OMAP from suspend.

Remove SYSCONFIG register configuration, omap hwmod framework will
use internal API to modify as required.
