Add hotplug support to mcp251x driver
Chip model can now be selected directly by matching the modalias name
(instead of filling the .model field in platform_data), and allows the
module to be auto-loaded. Previous behaviour is of course still supported.
Convert the two in-tree users to this feature (icontrol & zeus).
Tested on an Zeus platform (mcp2515).
