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
