b6288e236e drivers: add init and fini on octeontx2 NPA object
NPA object needs to initialize memory for queue interrupts context,
pool resource management, etc. This patch adds support for initializing
and finalizing the NPA object.

This patch also updates the otx2_npa_lf definition to meet the init/fini
requirements.

3da1b85b6d common/octeontx2: add FLR IRQ handler
Upon receiving FLR request from VF, It is PF responsibly
forward to AF and enable FLR for VFs.

This patch adds support for VF FLR support in PF.

This patch also add otx2_dev_active_vfs() API to find
the number of active VF for given PF.

05a58afca1 common/octeontx2: add uplink message support
The events like PHY link status change by AF or PHY configuration
change by PF would call for the uplink message.
The AF initiated uplink would land it in PF and PF would further
forward to VF(if it is intended for that specific VF)

The PF initiated uplink would be distributed to all active VFs.
This patch adds support for the same.

302e7d4958 common/octeontx2: add PF to VF mailbox IRQ and msg handlers
PF has additional responsibility being server for VF messages
and forward to AF and once AF process it then forward
the response back to VF.
otx2_vf_pf_mbox_irq() will process the VF mailbox request and
af_pf_wait_msg() will until getting a response back from AF.

9190acdd7a common/octeontx2: add AF to PF mailbox IRQ and msg handlers
This patch adds support for AF to PF mailbox interrupt and message
handling. PF writes the message on mapped mailbox region
followed by writing the mailbox doorbell register. Upon receiving,
the mailbox request in AF(In Linux kernel), It processes the messages
and update the counter memory and update the AF mbox doorbell
register. That would trigger a VFIO interrupt to userspace and
otx2_process_msgs() will handle it.

0e9734fe41 common/octeontx2: handle intra device operations
The mempool device(NPA) may be provisioned as a standalone device or
it can be part of ethdev/eventdev device. In order to address
mempool as standalone or integrated with ethdev/eventdev device,
An intra device structure being introduced.

When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA)
devices get probed by the eal PCI subsystem,
The NPA object(struct otx2_npa_lf) stored in otx2_dev base class.
Once it is accomplished, the other consumer drivers like
ethdev driver or eventdev driver use otx2_npa_* API to operate on
shared NPA object.

The similar concept followed for SSO object, Which needs to share between
PCIe devices.

c707a7332d common/octeontx2: add mailbox send and receive support
Each RVU device has a dedicated 64KB mailbox region
shared with its peer for communication. RVU AF has
a separate mailbox region shared with each of RVU PFs
and an RVU PF has a separate region shared with each of
it's VF.

This patch add use 64KB memory and implemented mailbox
send and receive support.

These set of APIs are used by this driver (RVU AF) and
other RVU PF/VF drivers eg ethdev, cryptodev e.t.c.

8a4f835971 common/octeontx2: add IO handling APIs
Various octeontx2 drivers use IO handling API, added octeontx2
specific IO handling routines in the common code.

Since some of those implementations are based on arm64 instructions
added the stub to compile the code on non arm64 ISA.
The non arm64 ISA stub is possible due to the fact that
it is an integrated controller i.e runs only on Marvell HW.

371d3212cb common/octeontx2: add build infrastructure and HW definition
Add the make and meson based build infrastructure along with
HW definition header file.

This patch adds skeleton otx2_mbox.c file to make sure
all header files are intact, subsequent patches add content
to otx2_mbox.c

This patch also updates CONFIG_RTE_MAX_VFIO_GROUPS
value to 128 as the system can have up to 128 PFs/VFs.
For octeontx2 meson build target, CONFIG_RTE_MAX_VFIO_GROUPS
defined as 128 so no additional changes required.
