Add keypad data node in omap5 device tree file.
Also fill the device tree binding parameters
with the required value in "omap5-evm" dts file.
Tested on omap5430 evm with 3.5 custom kernel.

This not a criticism on your patch, but a generic question about DT: Is there no way to have nice constants for keys like we have in the kernel, like KEY_POWER, KEY_UP, etc? If no, does DT allow comments so I can look at a dts and see which keycodes are mapped instead of having to dig up the sources?
