The remote spinlock was originally meant to synchronize access between
GPU and CPU accessing SMMU. However, there are more use cases that
this remote spinlock serves. This change decouples the spinlock from
GPU and adds support for taking the spinlock only for SMMUs that are
specified in the device tree.

Add Performance Monitor Unit (PMU) support for msm8610 IOMMU. The PMU
allows you to measure the performance of the IOMMU such as TLB miss
rate. The PMU for msm8610 can be configured to monitor the following
events:
-TLB Refill
-TLB Refill - Read
-Access
-Access - Write
-Number of Full Misses
