tkudav 0526e7eaa9 gpu: nvgpu: Create CIC-mon and CIC-rm subunits
common.cic unit is divided into common.cic.mon and common.cic.rm
based on rm and mon process split.

CIC-mon subunit includes the code which is utilized in critical
interrupt handling path like initialization, error detection and
error reporting path. CIC-rm subunit includes the code corresponding
to rest of interrupt handling(like collecting error debug data from
registers) and ISR status management (status of deferred interrupts).

Split the CIC APIs and data-members into above two subunits.
