Dirk van der Merwe 1489bbd10e nfp: use full 40 bits of the NSP buffer address 
The NSP default buffer is a piece of NFP memory where additional
command data can be placed.  Its format has been copied from
host buffer, but the PCIe selection bits do not make sense in
this case.  If those get masked out from a NFP address - writes
to random place in the chip memory may be issued and crash the
device.

Even in the general NSP buffer case, it doesn't make sense to have the
PCIe selection bits there anymore. These are unused at the moment, and
when it becomes necessary, the PCIe selection bits should rather be
moved to another register to utilise more bits for the buffer address.

This has never been an issue because the buffer used to be
allocated in memory with less-than-38-bit-long address but that
is about to change.

Fixes: 1a64821c6a ("nfp: add support for service processor access")
