ARM: OMAP4+: Cleanup the clocks layer

Browse Source 
Currently there is quite a lot of code which
is duplicated in the clocks code for OMAP 4 and 5
Socs. Avoiding this here by moving the clocks
data to a SOC specific place and the sharing the
common code.

This helps in addition of a new Soc with minimal
changes.
