Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

Implement some common default functions to enter and exit the
configuration state. Also provide default pnp_mode_ops for common
enter()/exit() function pairs.

In the file `COPYING` in the coreboot repository and upstream [1]
just one space is used.
The following command was used to convert all files.
$ git grep -l 'MA 02' | xargs sed -i 's/MA 02/MA 02/'

while others dislike them being extra commits, let's clean them up once and
for all for the existing code. If it's ugly, let it only be ugly once :-)

- Whitespace fixes, remove trailing whitespace, use TABs for identation
(except in Kconfig "help" lines, which start with one TAB and two spaces
as per Linux kernel style)
- Kconfig: Standardize on 'bool' (not 'boolean').
- s/lar/cbfs/ in one Kconfig help string.
- Reword various Kconfig menu entries for a more usable and consistent menu.
- Fix incorrect comment of NO_RUN in devices/Kconfig.
- superio/serverengines/Kconfig: Incorrect config name.
- superio/Makefile.inc: s/serverengine/serverengines/.
- superio/intel/Kconfig: s/SUPERIO_FINTEK_I3100/SUPERIO_INTEL_I3100/.
- mainboard/via/vt8454c/Kconfig: Fix copy-paste error in help string.
- mainboard/via/epia-n/Kconfig: Fix "bool" menu text.
- console/Kconfig: Don't mention defaults in the menu string, kconfig
already displays them anyway.
- Kill "Drivers" menu for now, it only confuses users as long as it's emtpy.
