Hi Marc,

Different compatible were used to distinguish since interrupt mapping
(PDC to GIC) was earlier kept in driver.

Now since mapping is kept in DTSI, we can continue to use
qcom,sdm845-pdc for sc7180.

i will submit another patch to make it more generic for all SoCs like
"qcom,pdc".

Thanks,

Maulik
