Subject[024/262] drm/radeon/kms: Fix I2C mask definitions
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Jean Delvare <jdelvare@suse.de>

commit 286e0c94f9c3f292cb38a977fbbde3433347a868 upstream.

Commit 9b9fe724 accidentally used RADEON_GPIO_EN_* where
RADEON_GPIO_MASK_* was intended. This caused improper initialization
of I2C buses, mostly visible when setting i2c_algo_bit.bit_test=1.
Using the right constants fixes the problem.
