Drop ACPI dependency for efi in linux-oniro and linux-yocto

qemuarm-efi is an efi machine that does not support ACPI. To fix this,
drop ACPI as a dependency in efi.cfg. This will not affect x86 machines
as ACPI is enabled by default for those. For arm64, apply an additional
patch that defaults to ACPI=y.

+Subject: [PATCH] efi.cfg: Drop ACPI dependency
+
+On X86 this will have no impact as CONFIG_ACPI is enabled by default. On
+the other hand, ARM64 would be affected as they don't have the same
+default. The defconfig for arm64 recommends CONFIG_ACPI and this patch
+follows this recommendation in the qemuarm64 bsp configuration to fix
+ACPI-only EFI boots on this arch.
+
+arm (32bit) would also be unaffected as there is no ACPI support there
+at all. And this unconditional drop (CONFIG_ACPI) will actually fix a
+configuration warning when enabling EFI on a arm (32bit) machine:
+
+[INFO]: config 'CONFIG_ACPI' was set, but it wasn't assignable, check
+(parent) dependencies
+
