Subject: [PATCH] ARM: OMAP2+: dpll: Add missing soc_is_am33xx() check for common functions

Add missing soc_is_am33xx() check for DPLL common control & clock
related functions, without this dpll programmability would be broken
for am33xx family of devices.

Not sure whether this should go as a fix in -rc, as AM33XX device
doesn't still boot without hwmod data (which is not yet upstream).
