ASoC: cs35l45: Select REGMAP_IRQ

commit d9ba297 upstream.

After commit 6085f9e ("ASoC: cs35l45: IRQ support"), without any
other configuration that selects CONFIG_REGMAP_IRQ, modpost errors out
with:

  ERROR: modpost: "regmap_irq_get_virq" [sound/soc/codecs/snd-soc-cs35l45.ko] undefined!
  ERROR: modpost: "devm_regmap_add_irq_chip" [sound/soc/codecs/snd-soc-cs35l45.ko] undefined!

Add the Kconfig selection to ensure these functions get built and
included, which resolves the build failure.
