regulator: mt6363: select CONFIG_IRQ_DOMAIN

When build-testing this driver without CONFIG_IRQ_DOMAIN causes
a compile-time error:

drivers/regulator/mt6363-regulator.c: In function 'mt6363_regulator_probe':
drivers/regulator/mt6363-regulator.c:884:18: error: implicit declaration of function 'irq_find_host' [-Wimplicit-function-declaration]
  884 |         domain = irq_find_host(interrupt_parent);
      |                  ^~~~~~~~~~~~~
drivers/regulator/mt6363-regulator.c:884:16: error: assignment to 'struct irq_domain *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
  884 |         domain = irq_find_host(interrupt_parent);
      |                ^
drivers/regulator/mt6363-regulator.c:896:30: error: implicit declaration of function 'irq_create_fwspec_mapping'; did you mean 'irq_create_of_mapping'? [-Wimplicit-function-declaration]
  896 |                 info->virq = irq_create_fwspec_mapping(&fwspec);
      |                              ^~~~~~~~~~~~~~~~~~~~~~~~~
      |                              irq_create_of_mapping

This is rather hard to trigger because so many other drivers
enable IRQ_DOMAIN already, but I ran into this on an s390
randconfig build.

Ensure this is always enabled using a Kconfig 'select IRQ_DOMAIN'
entry, as we do for all other users of this.
