gpu: nvgpu: 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 nvgpu 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.
