This patch prevents from the situation where we may end up with garbage
displayed on the LCD panel.
Such situation occurs when one performs "reboot -f" in Linux and then
stop in U-boot (or observe the garbage on the screen during boot up).
To prevent from such situation - the PWM pin is configured as GPIO and set
to LOW.

If many values differ from the defaults, overriding the full table

According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit
is set to 1 before the caches and MMU are enabled, or any cache and TLB
maintenance operations are performed".
ROM sets this bit in normal boot flow, but when in serial download mode,
it is not set.
Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms,
including mx7d, mx6ul/ull and mx7ulp.

This patch splits the current mini emmc configuration into emmc0
and emmc1 configurations because emmc is probed at boot time and on
systems which have only one interface mini configuration is failing on
unused interface. This patch also adds required clock node in dts and
enables CONFIG_MMC_SDHCI_ZYNQ through defconfig.

We currently handle the UEFI runtime reset / power off case handling via
a switch statement. Compilers (gcc in my case) may opt to handle these via
jump tables which they may conveniently put into .rodata which is not part
of the runtime section, so it will be unreachable when executed.
Fix this by just converting the switch statement into an if/else statement.
It produces smaller code that is faster and also correct because we no
longer refer .rodata from efi runtime code.

The mach/config.h file would helpfully define CONFIG_SYS_I2C and
CONFIG_SYS_I2C_MVTWSI if CONFIG_CMD_I2C was defined by the board. This
conflicts with the way DM_I2C works. As a transitional measure don't
automatically define these if CONFIG_DM_I2C is defined. It should be
possible to remove this once all kirkwood boards are migrated to DM.

There are a couple of open questions:
- do I need the u-boot,dm-pre-reloc tags in the device tree?
- should mach/config.h define CONFIG_DM_SEQ_ALIAS?
- how can we split this patch or are there any other pending patches
which does the same and I didn't catch these.
