Wield battle axe at ARM port

This patch unfortunately incorporates a number of changes,
all of which are making future ARM ports easier.

 - drop cruft that came in with u-boot
 - move serial console from mainboard Kconfig to Exynos Kconfig
 - factor out non-board specific wakeup code
 - move generic bootblock code from mainboard to Exynos
 - actually call arch_cpu_init()
 - remove dead code
 - fix up copyright messages
 - remove snow_ prefix from a lot of code to reduce the noise
   when creating a new mainboard based on that code.
