Subject: [PATCH] mfd: cs42l43: add REGMAP_IRQ requirement

The cs42l43 core uses devm_regmap_add_irq_chip(), so add REGMAP_IRQ
to what the core driver selects in order to provide this API.
This fixes a build error:

aarch64-linux-ld: drivers/mfd/cs42l43.o: in function `cs42l43_boot_work':
cs42l43.c:(.text+0x19d4): undefined reference to `devm_regmap_add_irq_chip'

Fixes: ace6d1448138 ("mfd: cs42l43: Add support for cs42l43 core driver")
