zork: add SSFC field for auto-mode speaker amp
This also converts the union with bitfields to explicit bit positions:
it's difficult to tell which bits are actually which when using bitfields,
because bitfield layout is implementation-defined (and in practice depends
on target endianness when building with GCC).
