drm/radeon/kms: i2c reorg
- keep the atom i2c id in the i2c rec - fix gpio regs for GPIO and MDGPIO on pre-avivo chips - track whether the i2c line is hw capable - track whether the i2c line uses the multimedia i2c block Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
