The Xtensa port was the only one remaining to be converted to the new way of connecting interrupts in Zephyr. Some things are still unconverted, mainly the exception table, and this will be performed another time. Of note: _irq_priority_set() isn't called on _ARCH_IRQ_CONNECT(), since IRQs can't change priority on Xtensa: while the architecture has the concept of interrupt priority levels, each line has a fixed level and can't be changed.
