meson: remove tag defined in KERNELBRANCH for 6.6 mainline kernel

[amazingfate]

Description

After we enable BTF for all families in #7629, mainline kernel 6.1/6.6 before v6.1.113/v6.6.54 can't load dkms module because of missing patch torvalds/linux@f34d086.
Deleting the line defining a tag to KERNELBRANCH can make us use branch linux-${KERNEL_MAJOR_MINOR}-y in linux-stable repo by default.

I use command git grep KERNELBRANCH|grep tag|grep -E "v6.1\.|v6.6" to find the tree families defining a tag for 6.1/6.6 kernel.

6.1 and 6.6 are lts kernel release long time ago and there should not be much change in the stable branch which can break our patches, and we can always keep the kernel up to date by using the linux-stable branch.

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.

• I have not tested because I don't have allwinner or amlogic boards.

Checklist:

Please delete options that are not relevant.

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• My changes generate no new warnings
• Any dependent changes have been merged and published in downstream modules

[The-going]

6.1 and 6.6 are lts kernel release long time ago and there should not be much change in the stable branch which can break our patches, and we can always keep the kernel up to date by using the linux-stable branch.

The 6.1 kernel is no longer supported by armbian and will be removed very soon.
In the process of further maintenance in the mainline core in version 6.6, some changes from the master branch will be applied. And it will overlap or conflict with our patches. Just trust me.

Usually the commits applied to linux-stable are necessary fix, and usually no changes to current kernel API. If that breaks our patch, we should fix ours.

The point of this is to adapt the patches to the new kernel version for sunxi-legacy, which is 6.1.125 today.
I don't want to do this today because it will be deleted tomorrow.

The tags for sunxi should be left off.

P.S. I want to limit my participation in the Armbian project to just putting the patches for sunxi
and some system scripts in order.
Configuration, build scripts, endless dependencies on third-party projects are all
the privilege of other maintainers and I do not interfere in this.
Sometimes I just pay attention to the problem, but give others the opportunity to make a decision.

Now this pr will only change meson family.
