Screen stays black after going idle or waking up from suspend on AMD

Bug description:
Upon upgrading to the latest HWE edge kernel (from 5.11 to 5.13) on
20.04, I found that my screen won't work if my laptop goes idle
(screen off) or wakes up from suspend. Reverting to 5.11 resolves this
for me.
This seems to be a common issue across many distributions and appears
to have been fixed in 5.14.
I'm using a ThinkPad P14s AMD Gen 1 with Ryzen 7 4750u (integrated
graphics).
