gm20b clocks is accessing thermal registers directly in several places.
Moved all this code to thermal unit and clock code is accessing these
through provided thermal hal functions.
Following new hal are defined in thermal unit for enabling/disabling
throttling and enabling/disabling idle slowdown:
void (*throttle_enable)(struct gk20a *g, u32 val);
int (*throttle_disable)(struct gk20a *g);
void (*idle_slowdown_enable)(struct gk20a *g, u32 val);
int (*idle_slowdown_disable)(struct gk20a *g);
At this moment, these hals are getting used only by gm20b code.
