> drm/i915/psr: Remove wait_for_idle() for PSR2
> CI runs show PSR2 does not go to IDLE with selective update enabled on
> all PSR exit triggers. Specifically, logs indicate the hardware enters
> "SLEEP Selective Update" and not "IDLE Reset state', like the kernel
> expects, when vblank interrupts are enabled. This check was added for PSR1
> but incorrectly extended to PSR2, remove the check as it breaks tests
> and prints out misleading error messages.
