drm/radeon/kms: add support for hw i2c on r1xx-r5xx
wire hw i2c support into radeon i2c algo. fixes merged: - handle bus probing correctly - use meaningful error numbers - abort if transaction fails - The line mapping is different depending on the asic. - protect hw i2c engine with a mutex - rs300 doesn't have a pin select bit - r200 has a different pin select setup Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
