[klibc] ARM: create /arch.cmd commands from firmware tags

ARM communicates with its firmware with a tagged data structure.
This takes appropriate chunks of the tagged data structure and converts
it to /arch.cmd options for kinit.

Bug report and initial patch by Thomas Gleixner <tglx@linuxtronix.de>,
significantly modified by me.
