[PATCH v3 5/9] capsule: kconfig: Select SET_DFU_ALT_INFO config symbol for capsule update

[Masami Hiramatsu]

Hi,

Even with this patch, if the platform configuration doesn't select
EFI_CAPSULE_FIRMWARE_* (or user will disable it when use it), the
platform will lose raw DFU availability.

Thank you,
