nvidia/tegra210: lp0_resume: clear the MC_INTSTATUS if MC_INTMASK was 0
The MC/SMMU should be resumed by the kernel. And the unexpected value
in the MC_INTSTATUS should be cleared before that. Or it will cause
some noisy MC interrupt once we enable the IRQ in the kernel.
BUG=chrome-os-partner:46796
BRANCH=none
TEST=LP0 suspend/resume test and the EMEM decode/arbitration errors
should not be observed on resume.
