soc/amd/common/lpc: use fixed_io_range_flags instead of open coding
Instead of open coding the same functionality, use fixed_io_range_flags to tell the resource allocator about the FCH subtractively decoding the first 0x1000 bytes of I/O space. Also update the comment to match the code. TEST=On Mandolin the flags of this resource stay the same (0xc0040100).
