This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

Switch the default CD GPIO polarity to active low.
The current hsmmc driver assumption that the CD GPIO is active high, but
in the real hardware, usually the opposite holds.
The usual SD card socket has a mechanical switch which is grounded as
soon as a card is inserted.
Of course there might be some board logic which inverts the signal, but
as far as current users are concerned, there is no such logic.
Current U-Boot users either not using the CD functionality, or have a
different way (e.g. external to SoC GPIO controller) for checking the
card presence.
This patch also brings the polarity assumption in line with the Linux
kernel and adds appropriate comments.
This patch also might spare issues once the TWL GPIO driver will be
converted to the DM.

Boot from eMMC boot partition corresponds to BOOT_DEVICE_MMC2
omap_bootmode, while BOOT_DEVICE_MMC2_2 corresponds to the user
data partition boot.
Fix mmc_get_env_part() boot mode check to use a correct value.

cm-t54 Eth MAC address is stored in onboard EEPROM.
Add EEPROM support and setup stored Eth MAC address.
If EEPROM does not contain a valid MAC, then generate it from the
processor ID code (reference code is taken from OMAP5 uEvm board file).
Modify Device Tree blob MAC address field with retrieved data.
