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.

Upon receiving notification from firmware the CGX event handler
in the AF driver gets the current link info such as status, speed,
duplex etc from CGX driver and sends it across to PFs who have
registered to receive such notifications.
To support above
- Mbox messaging support for sending msgs from AF to PF has been added.
- Added mbox msgs so that PFs can register/unregister for link events.
- Link notifications are sent to PF under two scenarioss.
1. When a asynchronous link change notification is received from
firmware with notification flag turned on for that PF.
2. Upon notification turn on request, the current link status is
send to the PF.
Also added a new mailbox msg using which RVU PF/VF can retrieve
their mapped CGX LMAC's current link info. Link info includes
status, speed, duplex and lmac type.

This patch adds support for setting MAC address filters in CGX
for PF interfaces. Also PF interfaces can be put in promiscuous
mode. Dataplane PFs access this functionality using mailbox
messages to the AF driver.

Firmware configures a certain number of MSIX vectors to each of
enabled RVU PF/VF. When a block LF is attached to a PF/VF, number
of MSIX vectors needed by that LF are set aside (out of PF/VF's
total MSIX vectors) and LF's msix_offset is configured in HW.
Also added support for a RVU PF/VF to retrieve that block LF's
MSIX vector offset information from AF via mbox.

This patch adds support for mailbox interrupt and message
handling. Mapped mailbox region and registered a workqueue
for message handling. Enabled mailbox IRQ of RVU PFs
and registered a interrupt handler. When IRQ is triggered
work is added to the mbox workqueue for msgs to get processed.

This patch adds mailbox support infrastructure APIs.
Each RVU device has a dedicated 64KB mailbox region
shared with it's peer for communication. RVU AF has
a separate mailbox region shared with each of RVU PFs
and a RVU PF has a separate region shared with each of
it's VF.
These set of APIs are used by this driver (RVU AF) and
other RVU PF/VF drivers eg netdev, crypto e.t.c.
