Previously, unit interrupt enabling/disabling and corresponding MC level interrupt enabling/disabling was not done at the same time. With this change, stall and nonstall interrupt for units are programmed at MC level along with individual unit interrupts. Kept access to MC interrupt registers through mc.intr_lock spinlock. For doing this separated CE and GR interrupt mask functions. mc.intr_enable is only used when there is global interrupt control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable is now removed. Removed following functions - mc_gv100_intr_enable, mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config as we can use the generic unit interrupt control function.
