GART static one time initialization was mixed up with GART

during suspend/resume cycles. This patch splits all GART

to free resources allocated by gart_init, gart_enable enable
the GART and is intented to be call after first initialization
and at each resume cycle or reset cycle. Finaly gart_disable

If it can't be found, then we will use the cvt/gtf to add the required mode.
If it can be found, it will be returned.
At the same time the function of drm_mode_vrefresh is also fixed. It will
return the result of actual refresh_rate plus 0.5.

When the calculated value is 84.9, then the fresh_rate is 85.
