graysky 3d631704a8 Add core/linux-rpi-16k
New kernel package providing 16k framesize for bcm2712/RPi5.  Very similar
to linux-rpi but built off bcm2712_defconfig.  Will work with Pi5 ONLY/will
not boot on lower models.

Since RPi Foundation has announced the 6.6 move[1] in the near future, just
start tracking that branch now.
