[PATCH 46/85] drivers: gpu: Move prototype declarations to header file radeon_mode.h from radeon_i2c.c

[Rashika Kheria]

Move prototype declaration of functions radeon_atom_hw_i2c_xfer() and
radeon_atom_hw_i2c_func() to header file drm/radeon/radeon_mode.h
because they are used by more than one file.

This eliminates the following warnings in drm/radeon/atombios_i2c.c:
drivers/gpu/drm/radeon/atombios_i2c.c:96:5: warning: no previous prototype for ‘radeon_atom_hw_i2c_xfer’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/atombios_i2c.c:146:5: warning: no previous prototype for ‘radeon_atom_hw_i2c_func’ [-Wmissing-prototypes]
