drivers: acpi: add dependency of EFI for arm64

BugLink: https://bugs.launchpad.net/bugs/1786878
As Ard suggested, CONFIG_ACPI && !CONFIG_EFI doesn't make sense on arm64,
while CONFIG_ACPI and CONFIG_CPU_BIG_ENDIAN doesn't make sense either.

As CONFIG_EFI already has a dependency of !CONFIG_CPU_BIG_ENDIAN, it is
good enough to add a dependency of CONFIG_EFI to avoid any useless
combination of configuration.

This bug, reported by Will, will be revealed when my patch series,
"arm64: kexec,kdump: fix boot failures on acpi-only system," is applied
and the kernel is built under allmodconfig.
