[PATCH v2 2/3] arm64: dts: qcom: purwa: Drop the Hamoa workaround for PDC

[Maulik Shah]

X1P42100 (Purwa) shares the X1E80100 (Hamoa) PDC device, but the hardware
register bug addressed in commit e9a48ea4d90b ("irqchip/qcom-pdc:
Workaround hardware register bug on X1E80100") is already fixed in
X1P42100 silicon.

X1E80100 compatible forces the software workaround. Use the X1P42100
specific compatible string for the PDC node to remove the workaround.

Fixes: f08edb529916 ("arm64: dts: qcom: Add X1P42100 SoC and CRD")
