msm: kgsl: Directly map and read soc hardware revision efuse

Directly map and read soc hardware revision efuse in kgsl driver
instead of reading it using nvmem and qfprom drivers. This helps
in avoiding dependency on nvmem and qfprom driver and defining
multiple dtsi properties to correctly read this efuse.
