[PATCH] gpio: gpio-reg: fix build

[Grygorii Strashko <grygorii.strashko@ti.com>]

Revert changes introduced by commit f0fbe7bce733 ("gpio: Move irqdomain
into struct gpio_irq_chip") as they are not aplicable to this driver.

Sorry, for inconvenience, but this driver has no users in lkml and
it can't be enabled through defconfig - only selected, so builds can't
be verified in standard way.
