Subject: [PATCH] arm64: Kconfig: Add SYS_SUPPORTS_APM_EMULATION

From: "Lecopzer Chen" <lecopzer.chen@...iatek.com>

Although most of modern devices use ACPI, there still has combination
of APM + ARM64.

In order to select CONFIG_APM_EMULATION, make SYS_SUPPORTS_APM_EMULATION
default is y if ACPI isn't configured.
