Subject[PATCH] arm64: fix ACPI dependencies
Date
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.

Fixes: 5bcd44083a08 ("drivers: acpi: add dependency of EFI for arm64")
