It was discovered that we couldn't skip the fastset on state
verification and hence this workaround is proposed.
First, the patch that skips state verifcation in case of
fastset is reverted. The second patch proposes the following
workaround by forcing full modeset for eDP when booting up.
GOP programs PLL parameters and hence, we would be able to
use fastset for eDP. However, with fastset we are not setting
PLL values from the driver and rely that GOP and driver PLL
values match. We have discovered that with some of the panels
this is not true and hence we would need to program PLL values
by the driver.
