TI keystone SoC updates for v6.6

 - Consolidation of files and drop pm_domain.c and keystone.h
ARM: keystone: Merge PM function into main support file

The one function left in this file does not justify a whole extra
file nor the keystone.h support file used to forward declare that
function. Merge this into the main keystone.c file.
