ARM: prepare for moving SoC sources into mach-*

In U-boot, the directory structure, arch/$(ARCH)/cpu/$(CPU)/$(SOC)/
has been adopted except that $(CPU) is missing from some
architectures and $(SOC) is missing from some CPUs.

This structure did not fit very well in some cases.

[1] AT91

AT91 SoC family have been developed across some ARM processor
generations.  Generally speaking, some IPs are often re-used in the
same SoC family (same SoC vendor) even when the main processor is
updated.  As a result, a SoC-common directory is needed in the upper
level.  Currently, AT91 source files are placed as follows:

  arch/arm/cpu/arm920t/at91/*
  arch/arm/cpu/arm926ejs/at91/*
  arch/arm/cpu/armv7/at91/*
  arch/arm/cpu/at91-common/*

Once directories are split, the motivation for refactorings across
CPU directories is lost.  Some files in arm920t/at91/ and
arm926ejs/at91/ are so similar that they could be merged.

[2] Tegra

Tegra is a little bit special case where different CPUs are used for
SPL and the main U-boot.  To obey the arch/$(ARCH)/cpu/$(CPU)/$(SOC)
structure, the source files must be placed across the CPUs,
again SoC-common directory is necessary in the upper level.

Moreover, there are several families in Tegra: Tegra20, Tegra30,
Tegra114, Tegra124.  Here again, the tegra-common directory is needed
to contain commonly-used files.

Tegra directories have been sprinkled in the directory structure.

  arch/arm/cpu/arm720t/tegra20
  arch/arm/cpu/arm720t/tegra30
  arch/arm/cpu/arm720t/tegra114
  arch/arm/cpu/arm720t/tegra124
  arch/arm/cpu/arm720t/tegra-common
  arch/arm/cpu/armv7/tegra20
  arch/arm/cpu/armv7/tegra30
  arch/arm/cpu/armv7/tegra114
  arch/arm/cpu/armv7/tegra124
  arch/arm/cpu/armv7/tegra-common
  arch/arm/cpu/tegra20-common
  arch/arm/cpu/tegra30-common
  arch/arm/cpu/tegra114-common
  arch/arm/cpu/tegra124-common
  arch/arm/cpu/tegra-common

As you see, splitting SoC code by the CPU is not going well,
especially for ARM.
Why don't we collect SoC-specific files into a single place?

A good example we can follow is Linux's arch/arm/mach-* structure.

This item was discussed in the following thread:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/188548/

Looks like I got some positive responses and we are almost ready to
start this movement.

This commit prepares arch/arm/Makefile for describing machdirs in it.

After this commit, we can move SoC directory to arch/arm/mach-$(SOC)
in simple steps although some cases such as AT91 and Tegra need more
fixes.

What we generally have to do is:

[1] Move files arch/arm/cpu/$(CPU)/$(SOC)/* to arch/arm/mach-$(SOC)/*
[2] Add machine entry into arch/arm/Makefile
[3] Remove "obj-y += $(SOC)" from arch/arm/cpu/$(CPU)/Makefile
[4] Fix the Kconfig file path in arch/arm/Kconfig
[5] Modify MAINTAINERS if necessary

serial: Support an early UART for debugging

This came up in a discussion on the mailing list here:

https://patchwork.ozlabs.org/patch/384613/

My concerns at the time were:
- it doesn't need to be written in assembler
- it doesn't need to be ARM-specific

This patch provides a possible alternative. It works by allowing any serial
driver to export one init function and provide a putc() function. These
can be used to output debug data before the real serial driver is available.

This implementation does not depend on driver model, and it is possible for
it to operate without a stack on some architectures (e.g. PowerPC, ARM). It
provides the same features as the ARM-specific debug.S but with more UART
and architecture support.

arc: introduce U-Boot port for ARCv2 ISA

ARC HS and ARC EM are new cores based on ARCv2 ISA which is binary
incompatible with ISAv1 (AKA ARCompact).

Significant difference between ISAv2 and v1 is implementation of
interrupt vector table.

In v1 it is implemented in the same way as on many other architectures -
as a special location where user may put whether code executed in place
(if machine word of space is enough) or jump to a full-scale interrupt
handler.

In v2 interrupt table is just an array of adresses of real interrupt
handlers. That requires a separate section for IVT that is not encoded
as code by assembler.

This change adds support for following cores:
 * ARC EM6 (simple 32-bit microcontroller without MMU)
 * ARC HS36 (advanced 32-bit microcontroller without MMU)
 * ARC HS38 (advanced 32-bit microcontroller with MMU)

As a part of ARC HS38 new version of MMU (v4) was introduced.

Also this change adds AXS131 board which is the same DW ARC SDP base board but
with ARC HS38 CPU tile.
