MLK-21368 staging: typec: tcpci: disable irq when system suspend
Disable typec irq when suspend to avoid the threaded irq to access
some resource(e.g. i2c over rpmsg) but those resource is not
available at later phrase, also use IRQ_DISABLE_UNLAZY flag to
mask the irq on irq chip level when irq happens.
