ath11k-qca6390-bringup-202012140938: rebate to v5.10 and MHI M2 workaround

[Kalle Valo]

(Bcc: people reporting qca6390 problems)

Hi,

there are updates in ath11k-qca6390-bringup branch[1] and the new tag
is:

ath11k-qca6390-bringup-202012140938

The changes are:

* rebase to v5.10 released last night

* remove unneeded patch "HACK: ath11k: add delays to suspend and resume handlers"

* add wink's workaround for MHI M2 issues: "HACK: mhi: disable M2 state"

* add workaround for 32M firmare memory problem: "HACK: Revert
  "mm/page_alloc: place pages to tail in __free_pages_core()""

* add patch: "ath11k: start vdev if a bss peer is already created"

All feedback very welcome, both positive and negative. You can send
them privately to me or to the public ath11k list.

Especially I would like to hear how Dell XPS 13 9310 laptops are
behaving. I'm hoping that ath11k would be usable using this branch,
without any extra patches or memmap hacks. If I get positive feedback
my plan is to send "dummy instructions" for a wider audience how to
use QCA6390 on Dell laptops with Linux.

In the reports try to include at least:

* name of the bringup branch tag you used

* if there are other changes in the kernel, patches, reverts etc

* do you use the memmap kernel parameter

* make and model of the laptop/computer (eg. Dell XPS 13 9310)

* how much testing you did

All feedback is very valuable and gives us guidance on what we need to
focus on.
