usb: typec: tipd: fix event checking for tps25750

In its current form, the interrupt service routine of the tps25750
checks the event flags in the lowest 64 bits of the interrupt event
register (event[0]), but also in the upper part (event[1]).

Given that all flags are defined as BIT() or BIT_ULL(), they are
restricted to the first 64 bits of the INT_EVENT1 register. Including
the upper part of the register can lead to false positives e.g. if the
event 64 bits above the one being checked is set, but the one being
checked is not.

Restrict the flag checking to the first 64 bits of the INT_EVENT1
register.
