input: qpnp-power-on: Add debounce for KPDPWR_N rising edge

On certain PMICs, an unexpected assertion on KPDPWR_DBC may
be seen during falling edge of KPDPWR_N when it is closer
to the rising edge of SLEEP_CLK. This triggers spurious
KPDPWR interrupts. Handle this by adding a debounce in SW
when the first KPDPWR_N falling edge is seen.

The debounce logic is enabled by the DT property
'qcom,kpdpwr-sw-debounce'.
