[PATCH 47/85] drivers: gpu: Move prototype declarations to appropriate header file radeon_asic.h

[Rashika Kheria]

Move prototype declarations of functions si_vram_gtt_location(),
si_rlc_reset(), si_init_uvd_internal_cg(), si_get_csb_size(),
si_get_csb_buffer(), si_gpu_check_soft_reset() and si_update_cg() to
header file drm/radeon/radeon_asic.h because they are used by more than
one file.

Also, include the header file in drm/radeon/si_dpm.c because it uses the
functions declared in the header file.

This eliminates the following warnings in drm/radeon/si.c:
drivers/gpu/drm/radeon/si.c:3510:5: warning: no previous prototype for ‘si_gpu_check_soft_reset’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:3818:6: warning: no previous prototype for ‘si_vram_gtt_location’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:4786:6: warning: no previous prototype for ‘si_init_uvd_internal_cg’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:5211:6: warning: no previous prototype for ‘si_update_cg’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:5277:5: warning: no previous prototype for ‘si_get_csb_size’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:5309:6: warning: no previous prototype for ‘si_get_csb_buffer’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/si.c:5398:6: warning: no previous prototype for ‘si_rlc_reset’ [-Wmissing-prototypes]
