pmdomain: apple: Drop default ARCH_APPLE in Kconfig

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.
