soc: fsl: dpio: keep a per dpio device MC portal
At the moment, the dpio-driver allocates an MC portal at probe time and
frees it right after usage. The same thing happens on the remove path.
This behavior could lead to scenarios where an MC portal is available
for use at probing but not longer free on the remove path which could
lead to unproper unbind of resources.
Change the driver's behavior in such a way that an MC portal is
allocated at probe and kept until the DPIO device is removed. This will
ensure that at any time after a DPIO device was successfully probed, all
its dependencies will be met.
