Mario Limonciello e4678483f9 platform/x86/amd: pmc: Add a workaround for an s0i3 issue on Cezanne
Cezanne platforms under the right circumstances have a synchronization
problem where attempting to enter s2idle may fail if the x86 cores are
put into HLT before hardware resume from the previous attempt has
completed.

To avoid this issue add a 10-20ms delay before entering s2idle another
time. This workaround will only be applied on interrupts that wake the
hardware but don't break the s2idle loop.
