FROMLIST: dt-bindings: interrupt-controller: qcom,pdc: Document x1p42100 PDC

Purwa shares the Hamoa (X1E80100) PDC device, but the hardware register
bug addressed in commit e9a48ea ("irqchip/qcom-pdc: Workaround
hardware register bug on X1E80100") is already fixed in Purwa silicon.

Hamoa compatible forces the software workaround. Add PDC compatible
for purwa as "qcom,x1p42100-pdc" to remove the workaround from Purwa.

Fixes: f08edb5 ("arm64: dts: qcom: Add X1P42100 SoC and CRD")
