Enable tegra based keyboard controller and populate the key mapping
for whistler.

With this patch, HOME, BACK, POWER and MENU keys will work.
Still other keys which are in ROW3 and ROW4 will not work as it
conflicts with KBC pins on SDIO2 pinmux.

Stephen,
Not tested the change but I reviewed all possible configuration like pinmux and
the parameter as per the downstream.
Request you to give a try.
