arm64: dts: qcom: sc8280xp-pmics: fix pon compatible and registers

The pmk8280 PMIC PON peripheral is gen3 and uses two sets of registers;
hlos and pbs.

This specifically fixes the following error message during boot when the
pbs registers are not defined:

	PON_PBS address missing, can't read HW debounce time

Note that this also enables the spurious interrupt workaround introduced
by commit 0b65118e ("Input: pm8941-pwrkey - add software key press
debouncing support") (which may or may not be needed).
