[PATCH 48/85] drivers: gpu: Move prototype declaration to header file radeon_asic.h from ci_dpm.c, cik_sdma.c, evergreen.c and kv_dpm.c

[Rashika Kheria]

Move prototype declaration of functions cik_gpu_check_soft_reset(),
cik_enter_rlc_safe_mode(), cik_exit_rlc_safe_mode(), cik_update_cg(),
cik_init_cp_pg_table(), cik_get_csb_size() and cik_get_csb_buffer() 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/ci_dpm.c because it uses
functions declared in the file.

This eliminates the following warning in
drivers/gpu/drm/radeon/cik.c:4648:5: warning: no previous prototype for ‘cik_gpu_check_soft_reset’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik.c:5481:6: warning: no previous prototype for ‘cik_enter_rlc_safe_mode’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik.c:5502:6: warning: no previous prototype for ‘cik_exit_rlc_safe_mode’ [-Wmissing-prototypes]

drivers/gpu/drm/radeon/cik.c:6028:6: warning: no previous prototype for ‘cik_init_cp_pg_table’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik.c:6239:5: warning: no previous prototype for ‘cik_get_csb_size’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/cik.c:6271:6: warning: no previous prototype for ‘cik_get_csb_buffer’ [-Wmissing-prototypes]
