arm64: fix ACPI dependencies
Kconfig reports a warning on x86 builds after the ARM64 dependency was added. drivers/acpi/Kconfig:6:error: recursive dependency detected! drivers/acpi/Kconfig:6: symbol ACPI depends on EFI This rephrases the dependency to keep the ARM64 details out of the shared Kconfig file, so Kconfig no longer gets confused by it. For consistency, all three architectures that support ACPI now select ARCH_SUPPORTS_ACPI in exactly the configuration in which they allow it. We still need the 'default x86', as each one wants a different default: default-y on x86, default-n on arm64, and always-y on ia64.
