usb: host: xhci-tegra: Drop using of_irq_parse_one()

Drivers generally shouldn't be using of_irq_parse_one() directly as it
is a low-level interrupt parsing API. The exceptions are cases that need
the values from the 'interrupts' property.

This is not the case for Tegra XHCI driver as it just uses
of_irq_parse_one() to test for 'interrupts' being absent or invalid.
Instead, just make the interrupt optional on any error other than
deferred probe. The exact reason for failing to get the interrupt is not
that important.
