commit: http://git.buildroot.net/buildroot/commit/?id=38c9ac40f9fc0e49c02bc56faee493d5dedb7332
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Remove low-level settings from config.txt like arm_freq and sdram_freq.
The defaults should be good for most and differ by Pi model.
E.g. the Pi 2 runs at 900 Mhz by default, setting arm_freq=700
like we had previously would underclock it.

Add short description in comments to options.
Mention initramfs option.

Remove obsolete options from cmdline.txt
