[PATCH 0/3] ASoC: fsl: fix missing GENERIC_BITREVERSE and 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 3 drivers, so they are here as one series.

Affected: fsl_aud2htx, fsl_xcvr, lpc3xxx-i2s.

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, x86_64, 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/.
