Move interrupt specific data-members from common.mc to common.cic Some of these data members like sw_irq_stall_last_handled_cond need To be initialized much earlier during the OS specific init/probe stage. Also, some more members from struct nvgpu_interrupts(like stall_size, stall_lines[]), which will soon be moved to CIC will also need to be initialized early during the OS specific probe stage. However, the chip specific LUT can only be initialized after the hal_init stage where the HALs are all initialized. Split the CIC init to accommodate the above initialization requirements.
