mac80211: switch to upstream owl-loader driver

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: misc: owl-loader for delayed Atheros ath9k fixup
-
-Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
-need to be able to initialize the PCIe wifi device. Normally, this is done
-during the early stages of booting linux, because the necessary init code
-is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
-However,this isn't possible for devices which have the init code for the
-Atheros chip stored on NAND in an UBI volume. Hence, this module can be
-used to initialze the chip when the user-space is ready to extract the
-init code.
