[ofw] Mlx4 driver support

[Leonid Keller]

MLX4 HCA driver (mlx4_hca.sys) is HW-agnostic, it works with a virtual
HCA device.
MLX4 BUS driver (mlx4_bus.sys) supports this device - see mlx4_bus.inx:

[MLX4BUS.DeviceSection.ntamd64]
...
%MT26428.DeviceDesc%=MLX4BUS.DDInstall, PCI\VEN_15B3&DEV_673c 

I guess, you get the error while an unattended install on some machine
with the remains of some old installation.
Try to install these same driver manually from Device Manager, while
providing to the installer the right mlx4_bus.inx file ...
