For each CGX LMAC that is mapped to a RVU PF, allocate
a pkind and config the same in CGX. For a received packet
at CGX LMAC interface this pkind is used by NPC block
to start parsing of packet.

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.

Added support in RVU AF driver to register for
CGX LMAC link status change events from firmware
and managing them. Processing part will be added
in followup patches.
- Introduced eventqueue for posting events from cgx lmac.
Queueing mechanism will ensure that events can be posted
and firmware can be acked immediately and hence event
reception and processing are decoupled.
- Events gets added to the queue by notification callback.
Notification callback is expected to be atomic, since it
is called from interrupt context.
- Events are dequeued and processed in a worker thread.

CGX LMAC initialization, link status polling etc is done
by low level secure firmware. For link management this patch
adds a interface or communication mechanism between firmware
and this kernel CGX driver.
- Firmware interface specification is defined in cgx_fw_if.h.
- Support to send/receive commands/events to/form firmware.
- events/commands implemented
* link up
* link down
* reading firmware version
