    arm: Redesign, clarify and clean up cache related code
    
    This patch changes several cache-related pieces to be cleaner, faster or
    more correct. The largest point is removing the old
    arm_invalidate_caches() function and surrounding bootblock code to
    initialize SCTLR and replace it with an all-assembly function that takes
    care of cache and SCTLR initialization to bring the system to a known
    state. It runs without stack and before coreboot makes any write
    accesses to be as compatible as possible with whatever state the system
    was left in by preceeding code. This also finally fixes the dreaded
    icache bug that wasted hundreds of milliseconds during boot.
