bus: fsl-mc: add fsl-mc userspace support
Adding userspace support for the MC (Management Complex) means exporting
an ioctl capable device file representing the root resource container.
This new functionality in the fsl-mc bus driver intends to provide
userspace applications an interface to interact with the MC firmware.
Commands that are composed in userspace are sent to the MC firmware
through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC
I/O portal is used for this operation, but if the implicit one is busy,
a dynamic portal is allocated and then freed upon execution.
