[PATCH 75/85] drivers: gpu: Move prototype declaration to header file radeon_asic.h from cik.c

[Rashika Kheria]

Move prototype declaration of functions cik_sdma_resume(),
cik_sdma_enable() and cik_sdma_fini() to header file
drm/radeon/radeon_asic.h because they are used by more than one file.

This eliminates the following warnings in drm/radeon/cik_sdma.c:
drivers/gpu/drm/radeon/cik_sdma.c:194:6: warning: no previous prototype for ‘cik_sdma_enable’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik_sdma.c:360:5: warning: no previous prototype for ‘cik_sdma_resume’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik_sdma.c:396:6: warning: no previous prototype for ‘cik_sdma_fini’ [-Wmissing-prototypes]
