Mohit Khanna 81179cb75e qcacmn: Fixes for IPA enablement for lithium/Hastings ...

- Support to pass IPA enabled(disabled) flag from ini to DP layer
- Use ioremap call to translate tx_comp_doorbell_paddr obtained from
  calling ipa_setup api to tx_comp_doorbell_vaddr. This is needed to
  write the initial value of HP at the doorbell address.
- Change REO_DST_RING_SIZE and WLAN_CFG_TX_RING_SIZE to 1023
  for napier/hastings if IPA is enabled. This is needed because,
  ipa_setup API can handle only 16-bit values for the size param(bytes)
  of the ring.
- Disable hash based flow steering for SAP peers in case IPA is enabled
  and set default reo_dest_ring_4 as default RX ring. Since IPA will be
  reaping RX packets from reo_dest_ring_4 only, flow steering is not
  needed for SAP peers.
- Unmap pre-allocated TX buffers for IPA in the TX completion ring.
- Donot execute IPA functionality if IPA is disabled from ini.
