Subject: [PATCH v7 00/12] wifi: ath12k: Add single wiphy support

With the introduction of Multi Link Operation (MLO) support in
IEEE802.11be, each EHT AP/non AP interface is capable of
operating with multiple radio links.

cfg80211/mac80211 expects drivers to abstract the communication
between such Multi Link HW and mac80211/cfg80211 since it depends
on different driver/HW implementation. Hence the single wiphy
abstraction with changes in datastructures were introduced in
"wifi: ath12k: Introduce hw abstraction"

This patchset extends the implementation to allow combination
of multiple underlying radios into a single composite hw/wiphy
for registration. Since now multiple radios are represented by
a single wiphy, changes are required in various mac ops that the
driver supports since the driver now needs to learn on how to tunnel
various mac ops properly to a specific radio.

This patchset covers the basic mac80211 ops for an interface bring up
and operation.

Note:
Monitor and hw reconfig support for Single Wiphy will be done in future
patchsets.

 v7:
 - Added get/put cache routines on PATCH 07/12

 v6:
 - Fixed print message typo in PATCH 05/12
 - Modified ath12k_mac_assign_vif_to_vdev() of PATCH 05/12 to
   not have multiple jump statements.
 - Modified PATCH 07/12 to have whole cache allocated dynamically &
   fixed cach flush in casewhere we reuese vdev created on scan.

 v5:
 - Addressed Jeff's comments
 - Made arvif config cache to be dynamic in PATCH 07/12

 v4:
 - Updated missing Signed-off details for patches.

 v3:
  - Rebased on ToT (added additional ar check in PATCH 08/12 for p2p)
  - Introduced iterator to loop through ars in an ah(for_each_ar())
  - Addressed comments on reverse xmas tree declaration style.

 v2:
  - Rebased on ToT and dependent patchset
