New kernel package for RPi5: linux-rpi-16k

[graysky]

Users of RPi5 can install the new [b]linux-rpi-16k[/b] kernel package which is compiled with 16k frame-size support. It is generated based off the bcm2712_defconfig rather than the bcm2711_defconfig. Only install this on RPi5. Lower models do not support the larger frame-size and will not boot.

You can confirm the 16k size once booted into the kernel by inspecting the output of:
[code]
% getconf PAGE_SIZE
16384
[/code]
