Made non-upstream patch design order aware (#14434)
- Why I did it

Currently, non upstream patches are applied only after upstream patches.

Depends on sonic-net/sonic-linux-kernel#313. Can be merged in any order, preferably together

- What I did it

Non upstream Patches that reside in the sonic repo will not be saved in a tar file bur rather in a folder pointed out by EXTERNAL_KERNEL_PATCH_LOC. This is to make changes to the non upstream patches easily traceable.
The build variable name is also updated to INCLUDE_EXTERNAL_PATCHES
Files/folders expected under EXTERNAL_KERNEL_PATCH_LOC
EXTERNAL_KERNEL_PATCH_LOC/
       ├──── patches/
             ├── 0001-xxxxx.patch
             ├── 0001-yyyyyyyy.patch
             ├── .............
       ├──── series.patch
series.patch should contain a diff that is applied on the sonic-linux-kernel/patch/series file. The diff should include all the non-upstream patches.
How to verify it

Build the Kernel and verified if all the patches are applied properly

Subject: [PATCH] devlink: add port to line card relationship set
In order to properly inform user about relationship between port and
line card, introduce a driver API to set line card for a port. Use this
information to extend port devlink netlink message by line card index
and also include the line card index into phys_port_name and by that
into a netdevice name.
