[PATCH] platform/x86/amd/pmc: Delay suspend for HP EliteBook 845 G10

[Konstantin Pospelov]

On the HP EliteBook 845 G10 (Ryzen 7 7840U), the CPU stays stuck at 544
MHz after resume from s2idle. Delaying suspend avoids this.

Tested with and without the patch over 6 cycles:
1. Suspend.
2. Connect the charger.
3. Resume.

The issue was reproduced 3 times, and was not reproducible 3 times with
the patch.
