Terje Bergstrom bc379d5eed gpu: nvgpu: Split L2 interrupt handling to MC and L2
L2 interrupt is processed by first reading from MC which L2 triggered
the interrupt and then calling a function per L2 slice to get the
details. Move the outer loop to MC unit, and the inner loop and L2
accesses to LTC unit.
