[PATCH 1/2] input: keypad: tc3589x: localize platform data

This driver can only get its platform data from the device tree,
and all platforms using it does that. Localize the platform data
for the keypad. A later patch will enforce the device tree / OF
dependence.

Dmitry it would be great if you could ACK this patch so Lee can
take it with the other patch through MFD.
