Move the calls to memcpy_fromio() up into the loop in dmi_scan_machine(), and move the signature checks back down into dmi_decode(). We need to check at 16-byte intervals but keep a 32-byte buffer for an SMBIOS entry, so shift the buffer after each iteration. Merge smbios_present() into dmi_present(), so we look for an SMBIOS signature at the beginning of the given buffer and then for a DMI signature at an offset of 16 bytes.
