For MDM platforms, set default REO destination
ring to SW4 for STA vdev, which is same as SAP vdev.
Note that RX hashing is still enabled for STA vdev.
Also REO destination are run-time remapped when IPA
automony is enabled and disabled.

Observed that when IPA offload is enabled, RX packets
are not routed correctly to IPA ring. Currently only
IX0 of REO_DESTINATION_CTRL_IX registers are remapped,
which only covers 3-bit reo_destination_indication of
range 0 to 7.
Fix is to remap REO_DESTINATION_CTRL_IX2|3 registers
so that reo_destination_indication of range 16 to
31 can also be routed REO2IPA ring when IPA offload
is enabled. Upon IPA offload is disabled, save values
of IX2 and IX3 are reset back to HW.

Support WDI 3.0 SW path intra-bss forwarding. Major
difference for WDI 3.0 is the metadata info passed
from ipa driver in skb->cb[].
Previously intra-bss fwd decision is done by FW and
it passes fw_desc to IPA where IPA driver passes onto
WLAN driver. Now for WDI 3.0, FW is not involved in RX
path and SW path intra-bss fwd decision has to be done
in wlan driver.

Support WLAN IPA WDI 3.0 with SMMU-S1 enabled. Key design
considerations are captured below.
- ring base addresses are passed as struct sg_table and IPA
driver will do the IOVA mapping to IPA domain.
- ring doorbell addresses are passed as physical address and
IPA driver will do the IOVA mapping to IPA domain.
- TX/RX buffers need to be mapped to IPA domain by WLAN driver
via ipa_wdi_create|release_smmu_mapping API.
- IPA doorbell addresses returned from ipa_wdi_conn_pipes are
DDR addresses and WLAN driver needs to do the IOVA mapping
to WLAN domain.

When IPA using GSI instead of UC different IPA TX and RX
clients needs to be configured. In this change when IPA
uses GSI configure appropriate TX and RX clients/pipes.

To abstract kernel header inclusion, create a new QDF APIs for all IPA
APIs and redirect all IPA API calls through QDF interfaces.
