These patches, along with an upcoming series for IGT, enable our PSR IGT tests to run reliably once again. The first change enables us to run the PSR tests on SKL and KBL RVP platforms, whose panels have too slow of a setup time when running in their preferred mode. The second fixes a minor problem with the way that we were initializing SRD_CTL that caused us to clobber a bit that we are not supposed to change in that register on SKL and KBL. The third change re-introduces some changes to our link training code to be less aggressive about changing link state for eDP, because PSR depends on the link state being the same at PSR exit as it was at PSR entry. The fourth change greatly increases the reliability of reading the sink CRC generated by the eDP panel.
