kernels: remove linux-libre-aarch64

This kernel has been replaced by linux-libre-64 in libre in
an attempt to unify all 64bit kernels made for 32bit
rootfs.

This has been tested on a SBC that has good upstream
support in linux and in u-boot, and a 64bit CPU.

That SBC is however not officially supported by Parabola
as it still require nonfree binaries in u-boot to boot.

The way to go to add official 64bit support ARM computers
with 64bit CPUs is to get devices that can at least boot
with fully free software.

Some SBCs with an Allwinner SOCs like the A64 seem a good
target to do that as some SBCs have good support in
upstream Linux and u-boot and can boot with free software,
and we already have an uboot4extlinux package for many
boards with Allwinner SOCs, so we could probably reuse most
of that work.

However I don't have an SBC like that yet, so until now I
tested on a board I was given at a conference.

-Subject: [PATCH 09/13] drm/i915: save AUD_FREQ_CNTRL state at audio domain
- suspend
-
-When audio power domain is suspended, the display driver must
-save state of AUD_FREQ_CNTRL on Tiger Lake and Ice Lake
-systems. The initial value of the register is set by BIOS and
-is read by driver during the audio component init sequence.
