gpio: pcf857x: select IRQ_DOMAIN
Patch 6e20a0a4 "gpio: pcf857x: enable gpio_to_irq() support"
added IRQ domain support to the pcf857x driver, but some configurations
(e.g. davinci_all_defconfig) don't already enable CONFIG_IRQ_DOMAIN.
Always selecting it from the Kconfig in this case is what other
such drivers do as well, and avoids these build errors:
Without this patch, building davinci_all_defconfig results in:
drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_to_irq':
