Li Zhou 92efe6f666 kernel-std: add initial version for debian packaging
Add kernel 5.10.74 debian packaging.

The kernel we are building starts as source code from the Yocto Project
kernel found at
(https://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto/about/?h=v5.10/standard/base).
To facilitate the creation of a Debian package of this kernel we start
by making a copy of the 5.10 Debian Bullseye 'debian' folder taken from
(http://snapshot.debian.org/package/linux/5.10.28-1/) and apply
customization via the meta-data patches in debian/deb_patches dir. In
this way we can review and incorporate changes the Debian community
makes to their kernel's 'debian' folder over time.

Since there are StarlingX specific patches to the kernel not suitable to
send for merging in linux-yocto we apply these here as defined in scope
and order in the contained debian/patches/series file.

Verification:
As we are only getting the Debian work bootstrapped there is quite a few
restrictions as far as what can be tested.

- I have compared it to the kernel 5.10.74 being used with stx centos:
  - the linux-yocto source code is same;
  - all the StarlingX specific patches are same;
  - the .config of Starlingx centos kernel 5.10.74 is taken to Starlingx
    debian, coexists and overrides the default debian kenrel configs,
    and only below changes are done for it:
    - remove some CONFIGs not set by Starlingx centos kernel code
      intentionally, such as CONFIG_CC_CAN_LINK;
    - remove some CONFIGs special for Starlingx centos kernel code such
      as: CONFIG_CC_VERSION_TEXT;
    - keep the CONFIGs related with signature aligned with debian
      release, because the security feature is still in development.
- 28 debs are built successfully. Build kernel image into rootfs and
  initramfs. Build the LAT ustart image from them.
- Use qemu to boot the ustart image, and the installer installs the
  rootfs successfully. The final debian system with this new kernel
  boot up successfully and run some simple commands successfully.

Subject: [PATCH 05/10] Make kernel start eth devices at offset
In order to avoid naming collisions, we want to make the kernel
start naming its "ethX" devices at eth1000 instead of eth0. This
will let us rename to a range starting at eth0.
