tegra132: Clean up clock register writes
Clean up functions to write to clk_enb and rst_dev registers and add
clock_disable and clock_set_reset functions to provide a complete API for
updating the registers.
BUG=chrome-os-partner:31821
BRANCH=None
TEST=Compiles successfully and boots to kernel prompt on ryu. Compiles
successfully on rush
