smadhavan a605a09e2a nvgpu: clk: MISRA Rule 21.2 header guard fixes
MISRA rule 21.2 doesn't allow the use of macro names which start with
an underscore. These leading underscores are to be removed from the
macro names. This patch will fix such violations in clk by renaming
them to follow the convention, 'NVGPU_PARENT-DIR_HEADER-NAME' when
there is no keyword repetition between file name and directory or
'NVGPU_HEADER-NAME' when there is repetition.
