EFI System Resource Table (ESRT) is an informational structure that
reports basic details about current system or device firmware. This is
chiefly used to perform firmware updates.
New CONFIG_DRIVERS_EFI_FW_INFO is off by default, enabling it adds
DRIVERS_EFI_FW_{GUID,VERSION,LSV} to be used to specify firmware
version/update information.
Existing forms of versions wouldn't be sufficient because there is no
universal way of converting string versions to 32-bit unsigned integers
and there are no GUIDs or lowest supported versions.
