usb: typec: tcpci_rt1711h: Unmask alert interrupts to fix functionality

commit d6b82dafd17db0658f089b9cdec573982ca82bc5 upstream.

During probe, the TCPC alert interrupts are getting masked to
avoid unwanted interrupts during chip setup: this is ok to do
but there is no unmasking happening at any later time, which
means that the chip will not raise any interrupt, essentially
making it not functional as, while internally it does perform
all of the intended functions, it won't signal anything to the
outside.

Unmask the alert interrupts to fix functionality.
