Most DPAA1 devices do not support a soft reset which is an issue if
Kexec starts a new kernel. This patch series allows Kexec to function
by detecting that the QBMan device was previously initialized.
The patches fix some issues with device cleanup as well as ensuring
that the location of the QBMan private memories has not changed
after the execution of the Kexec.
Changes since v1:
- Removed a bug fix and sent it separately to ease backporting
Changes since v2:
- Expliciitly flush FQD memory from cache on PPC before unmapping

soc/fsl/qbman: Rework QBMan private memory setup
soc/fsl/qbman: Cleanup buffer pools if BMan was initialized prior to
bootup

soc/fsl/qbman: Fix drain_mr_fqni()
soc/fsl/qbman: Disable interrupts during portal recovery
soc/fsl/qbman: Fixup qman_shutdown_fq()
