ASoC: snd-soc-lpass requires REGMAP_MMIO

With CONFIG_SND_SOC_LPASS_RX_MACRO=m and CONFIG_REGMAP_MMIO undefined,
build fails with the following error

  make -f /var/tmp/portage/sys-kernel/stable-sources-5.12.8/work/linux-5.12.8-stable/scripts/Makefile.modpost
    sed 's/\.ko$/\.o/' modules.order | scripts/mod/modpost   -E  -o modules-only.symvers -i vmlinux.symvers   -T -
  ERROR: modpost: "__devm_regmap_init_mmio_clk" [sound/soc/codecs/snd-soc-lpass-rx-macro.ko] undefined!

This does also apply to other Qualcomm Macro LPASS all making call to
devm_regmap_init_mmio()
