Current Kconfig menu at [ALSA for SoC audio support] has no rules.
So, some venders are using menu style, some venders are listed each drivers
on top page, etc. It is difficult to find target vender and/or drivers
because it is very random.

Let's standardize ASoC menu

When the first driver for Apple Silicon was upstreamed we accidentally
included `default ARCH_APPLE` in its Kconfig which then spread to almost
every subsequent driver. As soon as ARCH_APPLE is set to y this will
pull in many drivers as built-ins which is not what we want.
Thus, drop `default ARCH_APPLE` from Kconfig.

The MCA driver selects COMMON_CLK, which leads to misconfiguration
on platforms with HAVE_LEGACY_CLK (under compile test). Kconfig catches
the conflict with the following warning:

  WARNING: unmet direct dependencies detected for COMMON_CLK
  Depends on [n]: !HAVE_LEGACY_CLK [=y]
  Selected by [m]:
  - SND_SOC_APPLE_MCA [=m] && SOUND [=m] && !UML && SND [=m] &&
    SND_SOC [=m] && (ARCH_APPLE || COMPILE_TEST [=y])

Eventually the build fails with errors like:

>> drivers/clk/clk.c:867:6: error: redefinition of 'clk_unprepare'
     867 | void clk_unprepare(struct clk *clk)
         |      ^~~~~~~~~~~~~
   In file included from drivers/clk/clk.c:9:
   include/linux/clk.h:303:20: note: previous definition of 'clk_unprepare' with type 'void(struct clk *)'
     303 | static inline void clk_unprepare(struct clk *clk)
         |                    ^~~~~~~~~~~~~

which appears to be because COMMON_CLK is selected but HAVE_CLK_PREPARE
is not. In the end it seems we had no business selecting COMMON_CLK from
an unrelated driver like that, so remove the selection. The linux/clk.h
API is there anyway.
