On popular request this now completes the Warren's work started for
TK1:
aeb3fcb35956461077804720b8a252d50758d7e0
ARM: tegra: Use mem size from MC rather than ODMDATA
In addition to the move of using the Tegra memory controller (MC)
register rather than ODMDATA for T20, T30 and T114 as well it further
uses the generic get_ram_size() function (see "common/memsize.c")
<supposed to be used in each and every U-Boot port>TM. Added benefit is
that it should <catch 99% of hardware related (i. e. reliably
reproducible) memory errors> as well.
Thoroughly tested on the various Toradex line of Tegra modules
available which unfortunately does not include T114 and T124 (yet at
least) plus on the Jetson TK1.

In at least Tegra124, the Tegra memory controller (MC) has a register
that controls the memory size. Read this to determine the memory size
rather than requiring this to be redundantly encoded into the ODMDATA.
This way, changes to the BCT (i.e. MC configuration) automatically
updated SW's view of the memory size, without requiring manual changes
to the ODMDATA.
Future work potentially required:
* Clip the memory size to architectural limits; U-Boot probably doesn't
and won't support either LPAE or Tegra's "swiss cheese" memory layout,
at least one of which would be required for >2GB RAM.
* Subtract out any carveout required by firmware on future SoCs.

FUNCMUX_ defines should be named after the pin groups they affect, not
after the module they're muxing onto those pin groups.

IRDA is a synonym for UARTB in tegra pinmux, remove all usage of this
synonym and replace with UARTB to disambiguate.

Also made minor changes to shared Tegra code to support
T30 differences.

The prototypes used in board files were all scattered out, which lead to
code duplication between SPL and normal U-Boot and some prototypes not actually
being used. Consolidate this in a common board header.

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'
'root' file.
All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

patches.
Move files that are going to be common between T20 and T30 into 'tegra-common'
subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any
files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs
and modified for that SoC. The 'common' files should need only minor changes.
Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a
follow-on patch.
Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.
