fix LVDS setup on r4xx chips

R4xx mobility chips use atombios, which does not store the LVDS_GEN_CNTL
parameter setup like combios; rather, it's configured on fly in
LVDSEncoderControl.  As such, LVDS_GEN_CNTL is set wrong on resume.  Call
LVDSEncoderControl to set it properly.

This patch should fix the issue.  Another thing to try would be to try the
r4xx_atom module option; this forces the use of atom calls to set modes on r4xx
cards.
