Since we're about to start adding support for Intel's magic HDR
backlight interface over DPCD, we need to ensure we're properly
programming this field so that Intel specific sink services are exposed.
Otherwise, 0x300-0x3ff will just read zeroes.
We also take care not to reprogram the source OUI if it already matches
what we expect. This is just to be careful so that we don't accidentally
take the panel out of any backlight control modes we found it in.
v2:
* Add careful parameter to intel_edp_init_source_oui() to avoid
re-writing the source OUI if it's already been set during driver
initialization

UBUNTU: [Packaging] Disable udebs if $DEBIAN/d-i doesn't exist
Commit ("UBUNTU: [Packaging] replace custom filter script with dctrl-tools")
introduced the use of grep-dctrl which fails for a kernel that doesn't
build any udebs at all:
Because d-i/kernel-versions is empty in this case. With the previous commit
it is now possible to remove the d-i directory tree in kernels that don't
need/want udebs and use that as a global check to set disable_d_i=true.
While at it, add disable_d_i to the list of variables that printenv prints
out.
If the platform set the dyn_pcm_assign to true, it will call
hdmi_find_pcm_slot() to find a pcm slot when hdmi/dp monitor is
connected and need to create a pcm.
So far only intel_hsw_common_init() and patch_nvhdmi() set the
dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot
dynamically first, if the driver runs for a period of time and there
is no regression reported, we could set no_fixed_assgin to true in
the intel_hsw_common_init(), and then set it to true in the
patch_nvhdmi().
RFE type2 is a new NIC which has one RF antenna shares with BT.
Update phy parameter to verstion V57 to allow initial procedure
to load extra AGC table for sharing antenna NIC.

Incorrect CCK RSSI may cause periodically scan from upper layer.
8821c phy status does NOT has actual value of CCK power. It provides only
lna and vga index. Driver have to use these indexes to calculate
actual RSSI.

I overlooked the issue because when I was working on the said commit,
only the front audio is tested. Apology for that.
Changing supports_autosuspend in driver is too late for disabling
autosuspend, because it was already used by USB probe routine, so it can
break the balance on the following code that depends on
supports_autosuspend.
Fix it by using usb_disable_autosuspend() helper, and balance the
suspend count in disconnect callback.
