Subject: [PATCH] mfd: cs42l43: Fix Kconfig dependency

MFD_CS42L43 depends on REGMAP_IRQ as it uses devm_regmap_add_irq_chip.
Otherwise the build may fail with following log.

  AR      drivers/built-in.a
  AR      built-in.a
  AR      vmlinux.a
  LD      vmlinux.o
  OBJCOPY modules.builtin.modinfo
  GEN     modules.builtin
  MODPOST Module.symvers
ERROR: modpost: "devm_regmap_add_irq_chip" [drivers/mfd/cs42l43.ko] undefined!

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