Until we need real SMP on ARMv4, work around that situation

Instead of directly using the clk_src_id based on enum for clock source, every
device needs to have its own set of clk source ids defined. This prevents
accidentally selecting a wrong clk source if the ids are different from host1x's.
Also, clk_src_id is separated from clk_src_freq_id. clk_src_id is the clk src id
represented in CLK_SOURCE_<dev> registers, whereas clk_src_freq_id is used for
handling the common clock sources based on id to get the proper frequency in
software.
