[meta-virtualization][hardknott][PATCH 1/3] linux-yocto-dev, raspberrypi: apply fixed revision to kernel

[Christopher Clark <christopher.w.clark@gmail.com>]

The default preferred Linux kernel for Xen on the Raspberry Pi 4
board in this branch is linux-yocto-dev, which unfortunately results
in a branch tracking configuration rather than a fixed revision.

Apply a specified revision from the 5.12/standard/bcm-2xxx-rpi
branch, per the kernel version for this release, and disable tracking.
Revision is the current tip of v5.12/standard/bcm-2xxx-rpi branch,
tested and verified working on the board.
