The rocker device returns error codes if something goes wrong with descriptor
processing. Originally the device used standard errno codes for different
errors, but since those errno codes aren't portable across ARCHs, the device
now returns hard-coded error codes that stay constant across diff ARCHs. Fix
driver to use those same hard-coded values.

Rocker ports will use new "swdev" hwmode for bridge port offload policy.
Current supported policy settings are BR_LEARNING and BR_LEARNING_SYNC.
User can turn on/off device port FDB learning and syncing to bridge.

This patch introduces the first driver to benefit from the switchdev
infrastructure and to implement newly introduced switch ndos. This is a
driver for emulated switch chip implemented in qemu:
