The registers containing the touchkey status varies between
different chip revisions for the Zinitix touchscreens.

This series address the problem by reading out some chip
revision and firmware data so we can take different runtime
paths in different chip versions.

Also read out firmware and register version as this may
prove helpful to similar situations in the future.

This applies on top of Nikitas series to handle touchkeys
that was recently merged.

After this my BT404 touchkeys work.
