The driver assumed that I2C1 and I2C2 were always enabled,
and if they were not, then an asynchronous abort was (silently)
raised, to be caught much later on in the Linux kernel.
Fix this by making I2C1 and I2C2 optional just like I2C3 and I2C4
are.
To make the change binary-invariant, declare I2C1 and I2C2 in
every include/configs/ file which defines CONFIG_SYS_I2C_MXC.
Also, while updating README about CONFIG_SYS_I2C_MXC_I2C1 and
CONFIG_SYS_I2C_MXC_I2C2, add missing descriptions for I2C4 speed
(CONFIG_SYS_MXC_I2C4_SPEED) and slave (CONFIG_SYS_MXC_I2C4_SLAVE)
config options.

Change the default environment to use zImage instead of uImage, this
requires changes to the default environment to load a file named
zImage instead of uImage, and to use the 'bootz' command instead of
'bootm' when booting the kernel.
The zImage works for FSL Linux's kernel fork versions 3.0.35, 3.10.9,
and 3.10.17; this also works fine for mainline kernels.

This patch fixes allow for the DeviceTree and initrd relocation fixing
the boot of FSL 3.10.9-1.0.0-alpha kernel.
This changes following boards:
- mx6sabreauto
- mx6sabresd
- wandboard
- udoo
- nitrogen6x
- cgtqmx6eval
The reasoning, as explained by Hui Liu, is:
,----
| The FDT blob will be placed at DDR physical addr: 0x11000000. When Linux kernel
| Boot up, it will decompress the compressed kernel image and place the decompressed
| kernel image at the low end of the DDR memory and start running from it. If the
| decompressed kernel image is bigger for example than 16M, it may over written the
| fdt blob which u-boot loaded to the DDR memory @0x11000000 with fdt_addr=0x11000000
|
| To expand the fdt_addr from 0x11000000 to 0x18000000, which can avoid the override
| Since we will not likely have one kernel image larger than 128MB.

This issue is caused by the incorrect usage of CONFIG_SYS_MMC_ENV_PART.
CONFIG_SYS_MMC_ENV_PART should be used to specify the mmc partition that stores
the environment variables.
On some imx boards it is been incorrectly used to pass the partition of kernel
and dtb files for the 'mmcpart' script variable.
Remove the CONFIG_SYS_MMC_ENV_PART usage and configure the 'mmcpart' variable
directly.
