Subject: [PATCH 15/43] drm/radeon/atom: Move 'radeon_atom_hw_i2c_*()'s prototypes into shared header
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/radeon/atombios_i2c.c:100:5: warning: no previous prototype for ‘radeon_atom_hw_i2c_xfer’ [-Wmissing-prototypes]
100 | int radeon_atom_hw_i2c_xfer(struct i2c_adapter *i2c_adap,
| ^~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/radeon/atombios_i2c.c:150:5: warning: no previous prototype for ‘radeon_atom_hw_i2c_func’ [-Wmissing-prototypes]
150 | u32 radeon_atom_hw_i2c_func(struct i2c_adapter *adap)
| ^~~~~~~~~~~~~~~~~~~~~~~
