[acpi] Allow for extraction of a MAC address from the DSDT/SSDT

Some vendors provide a "system MAC address" within the DSDT/SSDT, to
be used to override the MAC address for a USB docking station.

A full implementation would require an ACPI bytecode interpreter,
since at least one OEM allows the MAC address to be constructed by
executable ACPI bytecode (rather than a fixed data structure).

We instead attempt to extract a plausible-looking "_AUXMAC_#.....#"
string that appears shortly after an "AMAC" or "MACA" signature.  This
should work for most implementations encountered in practice.
