Rework ehci-mxs so it supports both ports on MX28. It was necessary
to wrap the per-port configuration into struct ehci_mxs_port and pull
out the clock configuration function.

The ehci-mxs driver included the register definitions directly.
Use imx-regs.h instead since it contains proper handling of the

This patch streamlines the differences between the MX23 and MX28 by
implementing a few helper functions to handle different DMA channel
mapping, different clock domain for SSP block and fixes a few minor
bugs.
First of all, the DMA channel mapping is now fixed in dma.h by defining
the actual channel map for both MX23 and MX28. Thus, MX23 now does no
longer use MX28 channel map which was wrong. Also, there is a fix for
MX28 DMA channel map, where the last four channels were incorrect.
Next, because correct DMA channel map is in place, the mxs_dma_init_channel()
call now bases the channel ID starting from SSP port #0. This removes the
need for DMA channel offset being added and cleans up the code. For the
same reason, the SSP0 offset can now be used in mxs_dma_desc_append(), thus
no need to adjust dma channel number in the driver either.
Lastly, the SSP clock ID is now retrieved by calling mxs_ssp_clock_by_bus()
which handles the fact that MX23 has shared SSP clock for both ports, while
MX28 has per-port SSP clock.
Finally, the mxs_ssp_bus_id_valid() pulls out two implementations of the
same functionality from MMC and SPI driver into common code.

The real reason for memory instability was the fact that the EMI block
was gated and not reset throughout the boards' operation. This patch
resets the EMI block properly while also reverts the memory voltage bump.
The memory stability issues were caused by the EMI not being reset properly
and thus there is no longer need to run the memory at higher voltage than
it ought to run at.
This partly reverts 8303ed128a .

Rename all i.MX6 pad declarations to MX6_PAD_x, so a board
may support either i.MX6Quad/Dual (MX6Q) or i.MX6Dual-Lite/Solo
(MX6DL) by including the proper header.
Boards mx6qarm2, mx6qsabreauto, mx6qsabrelite, and mx6qsabresd
only support MX6Q, so they include mx6q_pins.h.

This does not actually change normal behaviour, but adds a check that
should detect corruption of relocation data (e.g. by using BSS data
prior to relocation).
Also add additional debugging output when enabled.
During this investigation, two situations have been seen:
1. calculate_relocation_address():
uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;
turns into
111166f: b8 83 c4 17 01 mov $0x117c483,%eax
whih is beyond the end of bss:
0117b484 g .bss 00000000 __bss_end
Somehow the __bss_end here is 255 bytes ahead.
2. do_elf_reloc_fixups():
uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;
Here the __text_start is 0 in the file:
1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx
1111da4: 81 ef 00 00 00 00 sub $0x0,%edi
As it happens, both of these are in pre-relocation code.
For these reasons we silent check and ignore bad relocations.

The memory layout calculations are done in calculate_relocation_address(),
and coreboot has its own version of this function. But in fact all we
really need is to set the top of usable RAM, and then the base version
will work as is.
So instead of allowing the whole calculate_relocation_address() function
to be replaced, create board_get_usable_ram_top() which can be used by
a board to specify the top of the area where U-Boot relocations to.

UBI can mount volumes by name or number The current code forces you
to name the volume by prepending every name with "ubi:".
>From fs/ubifs/super.c
* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
* o ubi:NAME - mount UBI device 0, volume with name NAME.
Now any name passed in any of the above forms are allowed.
Also update the configs that referenced ubifsmount.
