irqchip/qcom-pdc: Add purwa compatible for PDC secondary mode

Browse Source 
X1P42100 (Purwa) and X1E80100 (Hamoa) shares the same PDC and windows
firmware sets the PDC to secondary mode for X1P42100 too. Add support
to reset the PDC to pass through mode using qcom_scm_io_writel() similar
to X1E80100.

Make sure x1e_quirk to workaround a hardware bug is set only for X1E80100
as X1P42100 have this fixed in silicon.
