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.

This patch switches every last part of Coreboot on ARM over to Thumb
mode: libpayload, the internal libgcc, and assorted assembly files. In
combination with the respective depthcharge patch, this will switch to
Thumb mode right after the entry point of the bootblock and not switch
back to ARM until the final assembly stub that jumps to the kernel.
The required changes to make this work include some new headers and
Makefile flags to handle assembly files (using the unified syntax and
the same helper macros as Linux), modifying our custom-written libgcc
code for 64-bit division to support Thumb (removing some stale old files
that were never really used for clarity), and flipping the general
CFLAGS to Thumb (some more cleanup there as well while I'm at it).
BUG=None
TEST=Snow and Nyan still boot.

The ccopts mechanism is needed for passing ARM assembler flags to GCC.
There are many gotchas in adding ASFLAGS. As things have moved
around, the revert doesn't remove cleanly, so this reverts and cleans
up the ccopts.
This reverts commit 25b56c3af5.

acpigen_patch_len doesn't really need its argument: length always includes
everything from length bytes to current pointer and never bytes before it.
Hence just infer all the info implicitly.
Argument is wrong in several places through the codebase but ACPI parsing
is lax enough to swallow incorrect SSDT. After this function is used throughout
the codebase, these issues will be fixed.

The sizeof on array function parameter will return size of 'u8 *'
instead of 'spd_raw_data' (aka 'u8 [256]' leading to an overflow.
