Driver to enable the bus infrastructure for the Freescale
QorIQ Management Complex (fsl-mc). The fsl-mc is a hardware
module of the QorIQ LS2 SoCs, that does resource management
for hardware building-blocks in the SoC that can be used
to dynamically create networking hardware objects such as
network interfaces (NICs), crypto accelerator instances,
or L2 switches.

Only enable this option when building the kernel for
Freescale QorQIQ LS2xxxx SoCs.
