The qman portals are platform devices themselves, so they should
handle dma mappings.  Creating a dummy platform device in order to
support dma mapping operations is not justified (and not portable).
Instead, do the mapping against the first portal that has been
initialised.

qman_query_fq*() may return other error codes apart from
-ERANGE, in which cases the error handling done by the
resource cleanup callers would be wrong.  The patch
fixes the handling of those cases, and cleans up related
code inside the resource cleanup & release handlers (i.e.
replace hardcoded fqid value with corresponding define).

Version 3.00 of the ISA states that the PATS (partition table size) field
of the PTCR (partition table control register) and the PRTS (process table
size) field of the partition table entry must both be less than or equal
to 24. However the actual size of the partition and process tables is equal
to 2 to the power of 12 plus the PATS and PRTS fields, respectively. This
means that the max allowable size of each of these tables is 2^36 or 64GB
for both.

Thus when checking the size shift for each we should be checking for values
of greater than 36 instead of the current check for shifts larger than 24
and 23.

Currently there's some CMO (Cooperative Memory Overcommit) code, in
plpar_wrappers.h. Some of it is #ifdef CONFIG_PSERIES and some of it
isn't. The end result being if a file includes plpar_wrappers.h it won't
build with CONFIG_PSERIES=n.

Fix it by moving the CMO code into platforms/pseries. The two hcall
wrappers can just be moved into their only caller, cmm.c, and the
accessors can go in pseries.h.

Note we need the accessors because cmm.c can be built as a module, so
there needs to be a split between the built-in code vs the module, and
that's achieved by using those accessors.
