AMD AGESA Hudson: Include `stdint.h` and `io.h` to fix build

Apparently the files `smbus.{h,c}`, where never used and therefore
    build beforehand. Needing one function in them for the ASUS F2A85-M
    the build fails as some headers are missing. Including the headers
    `stdint.h` and `io.h` fixes the following errors.

Probably all the (AMD(?)) `smbus.{h,c}` suffer from this and
    should be fixed. Even better, as these function do not differ
    between most boards, the file should be moved out from the
    specific southbridge directories.
