thunderbolt, efi: Fix Kconfig dependencies harder
Since commitc9cc3aaa02
("thunderbolt: Use Device ROM retrieved from EFI"), the THUNDERBOLT config option selects APPLE_PROPERTIES. This broke the build for certain configs because APPLE_PROPERTIES is located in a menu which depends on EFI: If EFI is not enabled, the prerequisites needed for APPLE_PROPERTIES are not selected: Those are EFI_DEV_PATH_PARSER and UCS2_STRING. Additionally EFI_DEV_PATH_PARSER won't compile unless ACPI is enabled. Commit79f9cd35b0
("thunderbolt, efi: Fix Kconfig dependencies") sought to fix the breakage by making THUNDERBOLT select APPLE_PROPERTIES only if EFI_STUB is enabled. On x86, EFI_STUB depends on EFI and EFI depends on ACPI, so this fixed the build at least on this architecture. However on arm and arm64, EFI_STUB does not depend on EFI, so once again the prerequisites needed for APPLE_PROPERTIES are not selected. Additionally ACPI is not available on arm and optional on arm64, therefore EFI_DEV_PATH_PARSER won't compile. Fix by selecting APPLE_PROPERTIES only on x86.
