V2:
- Sets LINK_FAIL_TX_CNT to 1000 for all wcn36xx parts
- Uses wrapper function wcn36xx_enable_keep_alive_null_packet()
  around wcn36xx_smd_keep_alive_req()

Tested with:
'CNSS-PR-2-0-1-2-c1-74-130449-3' wcn3620
'CNSS-PR-2-0-1-2-c1-00083'       wcn3680

V1:
This patchset enables various firmware offload features for

- Link keepalive
- Link monitoring

Keepalive is a necessary precursor for an upcoming series on
wake on wlan, since we need to inform the firmware to keep the link up in
suspend.

Testing shows that LINK_FAIL_TX_CNT is a link monitor enable field. Once
set to non-zero link monitoring becomes active. This series activates
CONNECTION_MONITOR after enabling LINK_FAIL_TX_CNT thus offloading link
monitoring to the firmware.

  wcn36xx: Set LINK_FAIL_TX_CNT to 1000 on all wcn36xx
  wcn36xx: Enable firmware link monitoring
  wcn36xx: Enable firmware offloaded keepalive
