[PATCH] Revert "drm/msm/dp: set self refresh aware based on PSR support"

[Johan Hovold <johan+linaro@kernel.org>]

This reverts commit 1844e680d56bb0c4e0489138f2b7ba2dc1c988e3.

PSR support clearly is not ready for mainline and specifically breaks
virtual terminals which are no longer updated when PSR is enabled (e.g.
no keyboard input is echoed, no cursor blink).

Disable PSR support for now by reverting commit 1844e680d56b
("drm/msm/dp: set self refresh aware based on PSR support").

Bjorn reported that PSR support broke virtual terminals two months ago, 
but this is still broken in 6.4-rc3:

despite the following series that claimed to address this:

Let's revert until this has been fixed properly.
