drm/display: dp: change drm_dp_dpcd_read_link_status() return value

drm_dp_dpcd_read_link_status() follows the "return error code or number
of bytes read" protocol, with the code returning less bytes than
requested in case of some errors. However most of the drivers
interpreted that as "return error code in case of any error". Switch
drm_dp_dpcd_read_link_status() to drm_dp_dpcd_read_data() and make it
follow that protocol too.
