soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE usage
There is no reason to use RESERVEDMEM_OF_DECLARE() as the initialization
hook just saves off the base address and size. Use of
RESERVEDMEM_OF_DECLARE() is reserved for non-driver code and
initialization which must be done early. For qbman, retrieving the
address and size can be done in probe just as easily.
