gpu: nvgpu: Move Intr handling common code to CIC

Browse Source 
CIC (Central Interrupt controller) will be responsible for the
interrupt handling. common.cic unit is the placeholder for all
interrupt related code. Move interrupt related defines and
Public APIs present in common.mc to common.cic.
Note: The common.mc interrupts related struct definitions are
not moved as part of this patch.

Adapt the code to use interrupt handling related defines and public
APIs migrated from common.mc to common.cic
