rpi-firmware: modify settings for Pi 2
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 Signed-off-by: Floris Bos <bos@je-eigen-domein.nl> Reviewed-by: "Yann E.
