[PM-OPP][PATCH] OMAP: Add check for omap_device pointer before adding an opp

[Thara Gopinath <thara@ti.com>]

This patch adds the check for whether a omap_device and in turn
platform_device and device pointers exist for the device before
adding it's opp table into the global table. This is because all
the later accesses to the opp entries are based on dev pointer and
hence there is no point in adding a opp if the dev pointer does
not exist.
