    firmware-utils: Fix build failure in mkmerakifw.c FS#298
    
    Earlier compilers such as GCC 4 do not like anynomous unions, make it a named
    union "u", and update the code where relevant.
    
    Fixes FS#298
    Fixes: a72e1692b8b3 ("firmware-utils: Add support for the Cisco Meraki MX60/MX60W")
