Not all devices use proc_comm and determining if a clock is local vs. remote is fragile when done by comparing clk_ops pointers. Instead, implement an is_local() function for all clk_ops to determine if the clock is local. Doing this allows us to remove the last references to clk_ops_pcom from clock.c and compile it for targets with CONFIG_MSM_PROC_COMM=n. We don't need to set the clk_ops at runtime until 7x30 local clock detection comes in. Right now it's just complicating things so just set the ops pointer statically.
