gpu: nvgpu: add fuse clock support

Browse Source 
1) added support for fuse clock directly from nvgpu linux build for GV11B
and GP10B.
2) added a common function platform_acquire_clock thats used by both
GP10B, GV11B to acquire their respective clocks.
3) remove use of tegra_fuse_clock_enable/disable APIs

The clock parsing code is changed to verify the clock-names obtained
via DT with the static clock-names in the platform code before proceeding
with clk_enable.
