soc/amd/common/espi_util: espi_std_io_decode: fix edge case bug
When address and data register for the SIO control register access is passed as one I/O region with a size of 2, the corresponding special decode enable register should be used instead of a generic one to save the rather limited generic ones for other decode ranges.
