[PATCH 3/3] gpio: rockchip: use platform_get_irq() to retrieve interrupt

[Marco Scardovi <scardracs@disroot.org>]

The driver currently uses irq_of_parse_and_map() to parse and map the
GPIO bank interrupt from the device tree node. Since the bank device is
represented by a platform_device, use the standard platform_get_irq()
API instead. This integrates cleanly with the platform device framework
and ensures proper error propagation (such as -EPROBE_DEFER).
