msm: kgsl: Update global memory base to 0XFC000000 for 64bit kernel

Browse source 
KGSL memstore GPU address should be 32bit value for user mode
graphics driver to successfully mmap device memstore.

Move global memory base to 0XFC000000 from 0X100000000 for 64bit
kernel to allow user mode graphics driver to successfully mmap
memstore.
