[PATCH 74/85] drivers: gpu: Move prototype declarations to headerfile radeon.h from evergreen_hdmi.c

[Rashika Kheria]

Move prototype declarations of function
dce6_afmt_write_speaker_allocation(), dce6_afmt_write_sad_regs(),
dce6_afmt_select_pin() and dce6_afmt_write_latency_fields() to header
file drm/radeon/radeon.h because they are used by more than one file.

This eliminates the following warnings in drm/radeon/dce6_afmt.c:
drivers/gpu/drm/radeon/dce6_afmt.c:91:6: warning: no previous prototype for âdce6_afmt_select_pinâ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/dce6_afmt.c:107:6: warning: no previous prototype for âdce6_afmt_write_latency_fieldsâ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/dce6_afmt.c:150:6: warning: no previous prototype for âdce6_afmt_write_speaker_allocationâ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/dce6_afmt.c:196:6: warning: no previous prototype for âdce6_afmt_write_sad_regsâ [-Wmissing-prototypes]
