drm: fix regression in fb blank handling
commit 731b5a15a3b1474a41c2ca29b4c32b0f21bc852e
Author: James Simmons <jsimmons@infradead.org>

drm/kms: properly handle fbdev blanking
uses DRM_MODE_DPMS_ON for FB_BLANK_NORMAL, but DRM_MODE_DPMS_ON
is actually for turning output on instead of blank.
This makes fb blank broken on my T61, it put LVDS on but leave
pipe disabled which made screen totally white or caused some
'burning' effect.
[airlied: James objects to this but at this point in 2.6.33,
I can't see a patch that will fix this properly like he wants coming
in time and otherwise this is a regression - proper fix for 2.6.34
hopefully.]
