The following set of NPC registers allow the driver to configure NPC
to generate different key value schemes to compare against packet
payload in MCAM search.

NPC_AF_INTF(0..1)_KEX_CFG
NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG
NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG
NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG

Currently, the AF driver populates these registers to
configure the default values to address the most common
use cases such as key generation for channel number + DMAC.

The secure firmware stores different configuration
value of these registers to enable different NPC use case
along with the name for the lookup.

Patch loads profile binary from secure firmware over
the exiting CGX mailbox interface and apply the profile.

AF driver shall fall back to the default configuration
in case of any errors.

The AF consumer driver can know the selected profile
on response to NPC_GET_KEX_CFG mailbox by introducing
mkex_pfl_name in the struct npc_get_kex_cfg_rsp.

* Do CGX init before NIX init
  This would add consistency in NIX code that depends on cgx ports

* Few other misc cleanups
  - rvu_cgx_probe renamed as rvu_cgx_init for consistency
  - rvu_cgx_exit wrapper added to take care of the exit path
  - Added error check on cgx_lmac_event_handler_init
  - Minor cleanups in cgx.h related to tab alignment
  - Removed redundant ids from enum cgx_cmd_id

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
