gpu: nvgpu: add HAL to handle nonstall interrupts

Add new HAL gops.mc.isr_nonstall() to handle nonstall interrupts

We already handle nonstall interrupts in nvgpu_intr_nonstall()
But this API is completely in linux specific code

Separate out os-independent code to handle nonstall interrupts in new API
mc_gk20a_isr_nonstall() and set it to HAL gops.mc.isr_nonstall() for all
existing chips

Call this HAL from nvgpu_intr_nonstall()

Jira NVGPUT-8
