dtoverlays: Correct CSI2 settings for ov9281

OV9281 appears to drop the clock to LP mode between frames, but
the overlay didn't define this at both ends of the CSI2 link.
The overlay also had an incorrect link frequency defined, not that
the driver ever checked for one.

Fix both issues.

dts: bcm2711: Disable DVP by default

The HDMI DVP should be disabled by default as is the case for other
display related drivers. This changes resolves an issue when using
the legacy firmware display driver where the DVP caused the 108 MHz
clock in HDMI TX to be gated off when Linux started. This effectively
stopped the firmware from being able to change the HDMI analog PHY
registers.

Add a fragment to re-enable this in vc4-kms-v3d-pi4-overlay

Revert "ath9k: Fix general protection fault in ath9k_hif_usb_rx_cb"

This reverts commit b5c8896 which is
commit 2bbcaae upstream.

It is being reverted upstream, just hasn't made it there yet and is
causing lots of problems.

Mute bug fix for the Audioinjector.net isolated soundcard.

drm/vc4: Add FKMS as an acceptable node for dma ranges.

Under FKMS, the firmware (via FKMS) also requires the VideoCore cache
aliases for image planes, as defined by the dma-ranges under /soc.

Add rpi-firmware-kms to the list of acceptable nodes to look for
to copy dma config from.
