97777078d6 soc/fsl/qbman: Rework QBMan private memory setup
Rework QBMan private memory setup so that the areas are not
zeroed if the device was previously initialized

If the QMan private memory was already initialized skip the PFDR
initialization.

853dc104e6 soc: fsl: qbman: add APIs to retrieve the probing status
Add a couple of new APIs to check the probing status of qman and bman:
 'int bman_is_probed()' and 'int qman_is_probed()'.
They return the following values.
 *  1 if qman/bman were probed correctly
 *  0 if qman/bman were not yet probed
 * -1 if probing of qman/bman failed
Drivers that use qman/bman driver services are required to use these
APIs before calling any functions exported by qman or bman drivers
or otherwise they will crash the kernel.
The APIs will be used in the following couple of qbman portal patches
and later in the series in the dpaa1 ethernet driver.

37c342cba5 soc: Convert to using %pOF instead of full_name
Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

1f9c0a7727 soc/fsl: Introduce DPAA 1.x BMan device driver
This driver enables the Freescale DPAA 1.x Buffer Manager block.
BMan is a hardware accelerator that manages buffer pools.  It allows
CPUs and other accelerators connected to the SoC datapath to acquire
and release buffers during data processing.
