config: disable bnx2x driver
config: disable bnx2x driver

This driver has too many issues:
	- too big
	- bad coding style
	- no git history (dropped in 2 patches)
	- no documentation
	- no BSD support
	- no maintainer
And the biggest one, constraining this disabling:
	- many build issues

If the last 4 issues are not fixed in the next release 2.2,
the driver must be removed.
