ARM: dts: msm: Update bcl polling interval for PMI8994

Update the bcl Ibat and Vbat interrupt clear polling
interval to 100 millisecond for PMI8994.

This allows sufficient time for the BCL event to clear
before rearming the interrupt. This indirectly reduces
the oscillation between mitigation and clear sequence.
