Marco Felsch 7bec12fa98 usb: typec: tcpci: clear the fault status bit 
commit 23e60c8daf upstream.

According the "USB Type-C Port Controller Interface Specification v2.0"
the TCPC sets the fault status register bit-7
(AllRegistersResetToDefault) once the registers have been reset to
their default values.

This triggers an alert(-irq) on PTN5110 devices albeit we do mask the
fault-irq, which may cause a kernel hang. Fix this generically by writing
a one to the corresponding bit-7.
