[PATCH 2/2] wifi: ath11k: support ipq9574

The IPQ9574 can be coupled with wifi-6 chips, like QCN5024 to expose
a wifi device over AHB. Add the data structures necessarry to describe
the IPQ9574 wifi hardware.

The CE configs are identical to IPQ6018, as confirmed by inspecting
the out-of-tree qca-wifi-host-cmn (cnss2) driver.

Coldboot calibration does not seem to work. One of two issues are
seen. (1) The remoteproc firmware crashes with a fatal error, or
(2) the firmware stops sending qmi responses, appearing to hang. Leave
coldboot calibration disabled for now.

Tested-on: IPQ5974 WLAN.HK.2.9.0.1-01890-QCAHKSWPL_SILICONZ-1

Most information about the fields cames from the donwstream patch [1].
Analysis of the out-of-tree driver [2] shows that the IPQ9574 uses the
same CE configs as IPQ6018.
