This patch adds support for iMX6UL/ULL/SL/SDL MMDC into the DDR calibration
code. The difference between MX6DQ and MX6UL/ULL/SL is that the later SoCs
have 2 SDQS registers, just like MX6SX, while the MX6DQ/MX6SDL has 8.

The size of the binary created with the default U-boot config is much
greater than the default offset for environment `0x60000`.
In case if that binary is used for booting via MMC it is overlapped with
the environment stored on MMC.
This leads to U-Boot corruption while saving environment with `saveenv`
command and non-bootable SabreLite board.

The offset for environment `CONFIG_ENV_OFFSET=0x60000` was added in
commit a09fea1d but did not count in the change to `0xC0000` if option
`CONFIG_ENV_IS_IN_MMC` is used.

The offset is also used for variant with environment saving onto SPI NOR
flash (with enabled option `CONFIG_ENV_IS_IN_SPI_FLASH`). In that case the
U-Boot binary flashed on SPI NOR is also corrupted after environment
saving with the original 0x60000 offset.

Repair incorrectly negated condition in the original patch which broke
DT memory node parsing on everything which has more than one DT memory
node, e.g. R-Car3.

In case multiple valid memory nodes are present in the DT, the original
patch would complete parsing cycle for the first memory node, then move
on to the next one, identify it as a valid, and end the parsing. The fix
is to invert the condition, to make the code behave as it did before the
livetree conversion, so it would continue parsing the subsequent memory
nodes as well.

Since the introduction of 'get_cd' callback in sdhci core,
dragonboard410c's MMC interface is broken. It turns out that 'get_cd'
callback checks for the host_caps for validating the chip select. And
since the msm_sdhci driver is not parsing the host_caps from DT, not
all of the cababilities are parsed properly. This results in the MMC
interfaces to be broken.

Hence, fix this by adding a call to 'mmc_of_parse' during driver probe.
