Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.
This change is also coherent with the structure in kernel.

Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.
The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in
arch/{arm,nds32}/lib/asm-offsets.c.

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:
board/compulab/common/Makefile
board/udoo/Makefile
include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.
include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.
Note: 'git show' will also list two files just because
they are new:

Add the software workaround for ARM erratum ID 468414.
According to mx53/mx51 errata document:
"ENGcm11133 - ARM: NEON load data can be incorrectly forwarded to a
subsequent request
Description:
Under very specific set of conditions, data from a Neon load request can be incorrectly forwarded
to a subsequent, unrelated memory request.
The conditions are as follows:
• Neon loads and stores must be in use
• Neon L1 caching must be disabled
• Trustzone must be configured and in use
• The secure memory address space and the non-secure memory address space both use the same
physical addresses, either as an alias or the same memory location or for separate memory
locations
The issue is reported by ARM, erratum ID 468414, Category 2"

Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz.
Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz
instead.
Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI
at 1080p because the IPU clock cannot reach the requested frequency.
Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its
maximum frequency.
Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little
bit to allow easier comparison with the original clock setup from FSL U-boot.

Optimize mx5 lowlevel_init.S code size:
- Compute values at compile time rather than at runtime where possible.
- Assign r4 to hold the zero value rather than setting registers to 0 again and
again.
- Associate a function to setup_pll rather than expanding its large macro code
multiple times.
- Allocate constant values in section only if used.

The i.MX5 eSDHC clocks were considered as coming from the IPG clock although
they have dedicated clock paths.
Also, on i.MX5/6, each SDHC instance has a dedicated clock, so gd->sdhc_clk must
be set accordingly. This is good for the case only a single SDHC instance is
used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix
the multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).

This fixes the "IPG PERCLK" frequency printed by the clocks command. The issue

In the case periph_clk comes from periph_apm_clk, the latter is selected by the
CCM.CBCMR.periph_apm_sel mux, which can source the lp_apm clock from its

this case.

If CCM.CCSR.lp_apm is set, the lp_apm clock is not necessarily 32768 Hz x 1024.
In that case:
- on i.MX51, this clock comes from the output of the FPM,
- on i.MX53, this clock comes from the output of PLL4.
This patch fixes the code accordingly.
