Update the meta-lts-mixins layer

[quaresmajose]

In order to make the meta-lts-mixins/wrynose/linux-firmware layer
Yocto Project Compatible, the layer no more provide linux-firmware
by default unless that is explicitly stated in the variable
LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE.

Relevant changes for meta-lts-mixins:

• 7d003ac README: add LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE
• 2145371 linux-firmware: add LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE
• 6b8dd8b layer.conf: add LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE
• 11dcf7d SECURITY.md: describe security policy and pointers
• 9cab569 linux-firmware: set DEFAULT_PREFERENCE to "-1"
• b9d53c1 layer.conf: use the same priority as OE-Core

Fix #2457

This should be set via setting the DEFAULT_PREFERENCE in the bbappend

I've posted #2551 . Please consider that one.
Also, @quaresmajose , LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE doesn't fit the YP compatibility idea. Please revert those comments from the mixins layer.

[quaresmajose]

I'm trying to find a solution to the problem.

[quaresmajose]

I've posted #2551 . Please consider that one.

The mixins is already YP compatible given that it is passing the check layer with your change 11dcf7d SECURITY.md: describe security policy and pointers. But we can't use it as a dependency of meta-qcom, because when we add the override in meta-qcom to disable the DEFAULT_PREFERENCE = -1 of the mixins we break YP compat.

Also, @quaresmajose , LTS_LINUX_FIRMWARE_MIXIN_DEFAULT_PREFERENCE doesn't fit the YP compatibility idea. Please revert those comments from the mixins layer.

Replied on the mailing list:

I have merged these changes but this also breaks the Yocto Project Compatible check layer.
In reality, I think the concept of the mixin layer will always break the Yocto Project Compatible,
because the desire of the mixin layer is to introduce a more recent version of the one
provided by OE-core.

I'll have to revert those commits, but I'm looking for a way to do this while maintaining
the layer Yocto Project Compatible. If anyone has any suggestions, I would appreciate it.
