mac80211: add ath11k AHB support
This is the follow up to the PCI support commit now providing support for AHB variant as well, though currently only for ipq807x as that is only OpenWrt supported SoC ath11k supports as well. Currently, we are disabling coldboot calibration on ipq807x as it does not work, there is a remoteproc bug that makes it come late out of reset so disable coldboot until that is fixed. Also, as ath11k is quite memory hungry, we are introducing a config option to use the limits for 512MB of RAM, similar to what QCA does downstream but in way simpler and cleaner way so that 512MB save some RAM. 512MB profile is also set as the default for now.

+There is a bug with the remoteproc reset after coldboot calibration,

+Subject: [PATCH] ath11k: support setting FW memory mode via DT
+
+ath11k is really memory intensive for devices with less that 1GB of RAM,
+so lets allow saving a significant amount of memory by setting the FW to
+Mode-1 via DTS for devices that need it.
+
+However the drawback is reduced number of VDEV-s and peers which is a
+reasonable tradeoff.
+
+Mode-2 allows for further reduction, but it has further restrictions.
+
+While we are here, lets add a print to be able to easily determine what
+FW memory mode is being used.
