[PATCH RFC 01/13] ARM: OMAP2+: hwmod: AM335x: prepare for AM43x reuse

AM335x & AM43x have most of the interconnects, IPs similar. Instead of
adding new hwmod data for AM43x, reuse AM335x hwmod data as much as
possible.

In the hwmod entries that could be reused on AM43x, major changes are
in register offsets and different ocpif clock for most of peripherals
that comes under l4_wkup interconnect.

To achieve reuse, as a first step, bring out ocpif's relevant for both
SoC's to a new array and handle appropriately.
