usb: typec: Change power status check in tps6598x_interrupt

Since power status can change not only when
TPS_REG_INT_POWER_STATUS_UPDATE is set but also when
TPS_REG_INT_PP_SWITCH_CHANGED is set, check for power
status change also in the TPS_REG_INT_PP_SWITCH_CHANGED
case. In this way we detect power status change in some
cases where it was earlier undetected.

Fixes #250 and #291
