Moving to Common clk framework for OMAP would mean we no longer use
internal lookup mechanism like omap_clk_get_by_name().
get rid of all its usage mostly from hwmod and omap_device
code.

Also use IS_ERR_OR_NULL() for error checking.

This is wrong.  IS_ERR() is the only check you should ever use with clk_get().
