x86/microcode/AMD: Avoid -Wformat warning with clang-15

Older versions of clang show a warning for amd.c after a fix for a gcc
warning:

  arch/x86/kernel/cpu/microcode/amd.c:478:47: error: format specifies type \
    'unsigned char' but the argument has type 'u16' (aka 'unsigned short') [-Werror,-Wformat]
                           "amd-ucode/microcode_amd_fam%02hhxh.bin", family);
                                                       ~~~~~~        ^~~~~~
                                                       %02hx

In clang-16 and higher, this warning is disabled by default, but clang-15 is
still supported, and it's trivial to avoid by adapting the types according
to the range of the passed data and the format string.
