Implement a new "geomio" configuration argument to altera_avgen(4),
the generic I/O device we attach to various BERI peripherals. The new
option requests that, instead of exposing the underlying device via a
special device node in /dev, it instead be exposed via geom(4),
allowing it to be used with filesystems. The current implementation
does not allow a device to be exposed both for file/mmap and geom, so
one of the two models must be selected when configuring it via FDT or
device.hints. A typical use of the new option will be:
sri-cambridge,geomio = "rw";
