msm: kgsl: Change the base virtual address of MMU

Change the base virtual address of MMU to 0x10000000 instead of
0x66000000. Since, the IOMMU can map 2GB of address and the upper
address range from 0xC0000000 is reserved for global mappings, we
need to ensure that the base address plus the size of mapping
allowed i.e 2GB is less than 0xC0000000.
