drm/nouveau: Add some generic I2C gadget detection code.
Clean up and move the external TV encoder detection code to nouveau_i2c.c, it's also going to be useful for external TMDS and DDC detection. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
