[PATCH] gpio: synq: remove unused zynq_gpio_irq_reqres/zynq_gpio_irq_relres

From: Arnd Bergmann <arnd@arndb.de>

The driver now uses the generic request/release callbacks, so the custom
ones are no longer called. When building with -Woverride-init, gcc produces
a warning about the duplicate entries:

In file included from drivers/gpio/gpio-zynq.c:10:
include/linux/gpio/driver.h:621:43: error: initialized field overwritten [-Werror=override-init]
621 | .irq_request_resources = gpiochip_irq_reqres, \
| ^~~~~~~~~~~~~~~~~~~
drivers/gpio/gpio-zynq.c:611:9: note: in expansion of macro 'GPIOCHIP_IRQ_RESOURCE_HELPERS'
611 | GPIOCHIP_IRQ_RESOURCE_HELPERS,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/gpio/driver.h:621:43: note: (near initialization for 'zynq_gpio_level_irqchip.irq_request_resources')
621 | .irq_request_resources = gpiochip_irq_reqres, \
| ^~~~~~~~~~~~~~~~~~~
drivers/gpio/gpio-zynq.c:625:9: note: in expansion of macro 'GPIOCHIP_IRQ_RESOURCE_HELPERS'
625 | GPIOCHIP_IRQ_RESOURCE_HELPERS,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/gpio/driver.h:622:43: error: initialized field overwritten [-Werror=override-init]
622 | .irq_release_resources = gpiochip_irq_relres
| ^~~~~~~~~~~~~~~~~~~

Removing the old ones has no effect on the driver but avoids the warnings.
