[PATCH 0/4] ASoC: meson: fix missing REGMAP_MMIO dependencies

From: Jude Gyimah

Each of these drivers can be built into vmlinux while the code
providing a symbol it calls is a module, which fails to link. The
same shape in 4 drivers, so they are here as one series.

Affected: aiu, axg-pdm, axg-spdifin, axg-spdifout.

The fix is a select rather than a depends on: the providers have no
prompt of their own and are only ever enabled by a select, so a
depends on would leave these drivers unselectable.

Each was reproduced on v7.3, arm64 by a vmlinux link that failed on the
named symbol, and each links once the select is added.

Found with kreach, a static check that compares what Kconfig allows
against the symbols the compiled objects actually reference.

The checker is at https://github.com/JGyimah/kreach, and the
reproducer configuration for each finding is published with it
under results/.
