[PATCH] apple-gmux: Fix kconfig dependencies

[Seth Forshee]

Fix the dependencies of apple-gmux to prevent it from being built-in
when one or more of its dependencies is built as a module. Otherwise it
can fail to build due to missing symbols.

v2: Add dependency on ACPI to fix build failure when ACPI=n
