gpu: nvgpu: Move isr related fields from gk20a

Move fields in struct gk20a related to interrupt handling into
Linux specific nvgpu_os_linux. At the same time move the counter
logic from function in HAL into Linux specific code, and two Linux
specific power management functions from generic gk20a.c to Linux
specific module.c.
