[PATCH 30/85] drivers: gpu: Move prototype declarations to appropriate header file radeon.h

[Rashika Kheria]

Move prototype declaration to the header file drm/radeon/radeon.h from
files drm/radeon/cik.c, drm/radeon/r600_dma.c and drm/radeon/si.c
because they are used by more than one file.

This eliminates the following warnings in drm/radeon/r600.c:
drivers/gpu/drm/radeon/r600.c:1442:5: warning: no previous prototype for ‘r600_gpu_check_soft_reset’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/r600.c:3133:5: warning: no previous prototype for ‘r600_ih_ring_alloc’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/r600.c:3169:6: warning: no previous prototype for ‘r600_ih_ring_fini’ [-Wmissing-prototypes]
