[PATCH 3.13 167/172] drm/radeon: print the supported atpx function mask

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

commit 9f050c7f9738ffa746c63415136645ad231b1348 upstream.

Print the supported functions mask in addition to
the version.  This is useful in debugging PX
problems since we can see what functions are available.
