This patch adds support for a RVU PF/VF to disable all Aura/Pool
contexts of a NPA LF via mbox. This will be used by PF/VF drivers
upon teardown or while freeing up HW resources.
A HW context which is not INIT'ed cannot be modified and a
RVU PF/VF driver may or may not INIT all the Aura/Pool contexts.
So a bitmap is introduced to keep track of enabled NPA Aura/Pool
contexts, so that only enabled hw contexts are disabled upon LF
teardown.

Add support for a RVU PF/VF to submit instructions to NPA AQ
via mbox. Instructions can be to init/write/read Aura/Pool/Qint
contexts. In case of read, context will be returned as part of
response to the mbox msg received.

Upon receiving NPA_LF_ALLOC mbox message allocate memory for
NPALF's aura, pool and qint contexts and configure the same
to HW. Enable caching of contexts into NPA NDC.
Return pool related info like stack size, num pointers per
stack page e.t.c to the mbox msg sender.

Initialize NPA admin queue (AQ) i.e alloc memory for
AQ instructions and for the results. All NPA LFs will submit
instructions to AQ to init/write/read Aura/Pool contexts
and in case of read, get context from result memory.
Added some common APIs for allocating memory for a queue
and get IOVA in return, these APIs will be used by
NIX AQ and for other purposes.
