gpu: nvgpu: move linux clk calls to tegra specific file

clk_gm20b.c has number of calls specific to linux and
tegra-soc environment
In order to unify the driver, move all of those calls
to tegra/linux specific file tegra/linux/clk.c

All the clk_*() and tegra_dvfs_*() calls are now
abstracted behind GPU's clock operations and shoule be
accessed using g->ops.clk.<API> format

Remove <linux/clk.h> and <soc/tegra/tegra-dvfs.h> from
clk_gm20b.c

Remove <linux/version.h> from clk_gm20b.c too since
we only support k4.4 and higher version only
