drm/radeon/pm: adjust display configuration after powerstate
[ Upstream commit 39d4275058baf53e89203407bf3841ff2c74fa32 ]
set_power_state defaults to no displays, so we need to update
the display configuration after setting up the powerstate on the
first call. In most cases this is not an issue since ends up
getting called multiple times at any given modeset and the proper
order is achieved in the display changed handling at the top of
the function.
