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: move page tables to trustzone regionAaron Durbin
In order to access secure device register space the cpu needs to have the page tables marked as secure memory. In addition the page tables need to live within secure memory otherwise the accesses default to non-secure. Therefore move the page tables to the trustzone region. Remove the TTB_* config options as well as removing the TTB reservations from coreboot's resource list.

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.
