Merge request to ensure compatibility between men_lx_chameleon and mcb modules

If a PCI device was already "linked" with mcb-pci driver then when module men_lx_chameleon is loaded (modprobe), the pci_dev .probe function will never be called as the PCI devices already have a driver. In such case, for ensuring the MCB-MDIS compatibility, just search for Chameleon PCI devices and try to load the chameleon table explicitly.

Closes #248
