gpu: nvgpu: clean linux headers from clk_gk20a.h

gk20a/clk_gk20a.h is a common file but still includes linux specific headers
Clean them up as below

- put linux/clk-provider.h include under config CONFIG_COMMON_CLK
- move linux/clkdev.h include to common/linux/platform_gk20a_tegra.c as it is no
  longer needed in this file

Jira NVGPU-259
