mac80211: switch to upstream owl-loader driver

Browse Source 
The Owl Loader (named after the codename that Atheros gave
these devices back in the day) has been accepted upstream.

This patch removes the "misc" driver OpenWrt had and adds
the remaining differences against the version that ships
with 5.4-rc1 into a separate "120-owl-loader-compat.patch"
file that can be cut down once AR71XX is being dealt with.

Note: I decided to keep the existing (kmod-)owl-loader
package name around for now. The kernel module file in
the kmod package will be called ath9k_pci_owl_loader.ko
though.

Subject: [PATCH] ath9k: use iowrite32 over __raw_writel
To: linux-wireless@vger.kernel.org
Cc: QCA ath9k Development <ath9k-devel@qca.qualcomm.com>,
Kalle Valo <kvalo@codeaurora.org>,
Hauke Mehrtens <hauke@hauke-m.de>,
Mathias Kresin <dev@kresin.me>,
Martin Blumenstingl <martin.blumenstingl@googlemail.com>
This patch changes the ath9k_pci_owl_loader to use the
same iowrite32 memory accessor that ath9k_pci is using
to communicate with the PCI(e) chip.
This will fix endian issues that came up during testing
with loaned AVM Fritz!Box 7360 (Lantiq MIPS SoCs + AR9287).
Fixes: 5a4f2040fd07 ("ath9k: add loader for AR92XX (and older) pci(e)")
