platform: tegra: Make ADSP CPU driver a LKM

Browse Source 
-Made necessary Kconfig and makefile changes
 required to make ADSP CPU driver a loadable kernel
 module.
-Had to replace nsec_to_clock_t api with functions that are
 available as exported symbols as nsec_to_clock_t is not an
 exported symbol
