[PATCH v1 2/2] regulator: pf9453: Allow shared IRQ

[Franz Schnyder <fra.schnyder@gmail.com>]

From: Franz Schnyder <franz.schnyder@toradex.com>

The PF9453 datasheet specifies the IRQ_B pin as an open drain output
with level-low behavior. This makes it capable to share the interrupt
line.

Set the IRQF_SHARED to be able to share the interrupt line with
other devices.
