[PATCH 44/85] drivers: gpu: Move prototype declaration to header file radeon_mode.h from radeon_atombios.c and radeon_encoders.c

[Rashika Kheria]

Move prototype declarations of function radeon_add_atom_encoder() and
radeon_atom_backlight_init() to header file drm/radeon/radeon_mode.h
because they are used by more than one file.

This eliminates the following warning in drm/radeon/atombios_encoders.c:
drivers/gpu/drm/radeon/atombios_encoders.c:177:6: warning: no previous prototype for ‘radeon_atom_backlight_init’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/atombios_encoders.c:2600:1: warning: no previous prototype for ‘radeon_add_atom_encoder’ [-Wmissing-prototypes]
