[PATCH 1/2][SRU][OEM-5.14] UBUNTU: SAUCE: pinctrl: amd: Add irq field data

[Alex Hung]

From: Basavaraj Natikar <Basavaraj.Natikar at amd.com>

pinctrl_amd use gpiochip_get_data() to get their local state containers
back from the gpiochip passed as amd_gpio chip data.

Hence added irq field data to get directly using amd_gpio chip data.
