    AVR: Fix typo in device-specs generation.  Reuse -m[no-]rodata-in-ram checker.
    
    gcc/
            * config/avr/gen-avr-mmcu-specs.cc (diagnose_rodata_in_ram): Fix typo
            in the diagnostic, and capitalize the device name.
            (print_mcu): Generate specs such that:
            <*check_rodata_in_ram>: New.
            <*cc1_misc>: Use check_rodata_in_ram instead of cc1_rodata_in_ram.
            <*link_misc>: Use check_rodata_in_ram instead of link_rodata_in_ram.
            <*cc1_rodata_in_ram, *link_rodata_in_ram>: Remove.
