Subject: [PATCH 0/2] purwa: Drop the Hamoa PDC workaround from purwa

Purwa shares the Hamoa PDC compatible. Hamoa had the software workaround
added due to hardware register bug mentioned in commit [1] which used
Hamoa/X1E80100 compatible to apply the workaround.

As the hardware bug mentioned in [1] is fixed on purwa silicon add purwa
compatible to avoid applying workaround meant for hamoa.
