2015-03-27tegra132: Fix clock apisFurquan Shaikh
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.

2015-03-27tegra132: return actual plld frequencyAaron Durbin
Depending on the requested frequency the plld cannot necessarily obtain the exact clock. Therefore provide the closest configured frequency as a return value. This is equivalent to the t124 patch. BUG=chrome-os-partner:31640 BRANCH=None TEST=Built and noted plld actual value close to requested.

2015-03-27tegra132: separate/refactor clock enable/reset codeTom Warren
Added distinct functions for clock_enable and clock_clear_reset, and rewrote clock_enable_clear_reset() to use them. Useful when unpowergating SOR partition, for instance, where we need to enable a bunch of periph clocks, unclamp SOR, then take all of those periphs out of reset.
