gpu: nvgpu: ltc: create sub-unit for ltc intr

Browse Source 
Created sub-unit for ltc interrupt handling.
Following 2-hals are moved from ltc to ltc intr unit:
void (*isr)(struct gk20a *g, u32 ltc);
void (*en_illegal_compstat)(struct gk20a *g, bool enable)

Added new hal in ltc intr sub-unit for configuring ltc interrupts:
void (*configure)(struct gk20a *g);

Moved ltc interrupt related code from ltc to ltc intr unit.
Chip ltc.intr hals are populated with updated function names
created in ltc intr unit.

Converted all "unsigned int" usage to "u32" in ltc and ltc intr units
to match with hardware 32 bit register read/write.
