gpu: nvgpu: move gm20b clock register to platform file

We currently register gm20b clock operations gm20b_clk_ops
in function gm20b_register_gpcclk() which is in clk_gm20b.c

Since this is common clock framework and hence linux dependency,
move this clock registration to platform specific file

Note that all the clock operations remain in clk_gm20b.c.
APIs in platform file will eventually call operations
in clk_gm20b.c
