[PATCH 54/85] drivers: gpu: Move prototype declarations to header file rv770_dpm.h

[Rashika Kheria]

Move prototype declarations of functions rv770_get_ps(), rv770_get_pi()
and evergreen_get_pi() to header file drm/radeon/rv770_dpm.h because
they are used by more than one file.

This eliminates the following warnings in drm/radeon/rv770_dpm.c:
drivers/gpu/drm/radeon/rv770_dpm.c:47:18: warning: no previous prototype for ‘rv770_get_ps’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/rv770_dpm.c:54:26: warning: no previous prototype for ‘rv770_get_pi’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/rv770_dpm.c:61:30: warning: no previous prototype for ‘evergreen_get_pi’ [-Wmissing-prototypes]
