msm: kgsl: Lock ringbuffer translation in TLB 



Lock ringbuffer virtual address translation in TLB of IOMMU. This
is required to prevent a hardware table walk from happening when
GPU executes commands that program the IOMMU registers. If a hardware
table walk happens when GPU is programming IOMMU register then it
can cause a deadlock on the bus.
