drivers: gpio_cc32xx: avoid unnecessarily disabling interrupts in isr

In the gpio isr, gpio interrupts are disabled when invoking the
registered callbacks. This is unnecessary, and causes a problem if the
callback attempts to disable gpio interrupts by reconfiguring the pin
as in the test gpio_basic_api.

Fixes zephyrproject-rtos#22847
