Add support for reading devicetree flags for MMC devices. With this we
can distinguish between fixed and removable drives. Note that this
information is only available when the device is probed, not when it is
bound, since it is read in the of_to_plat() method. This could be changed
if needed later.

At present if a driver is missing a uclass or compatible stirng, this
is silently ignored. This makes sense in most cases, particularly for
the compatible string, since it is not required except when the driver
is used with of-platdata.

But it is also not very helpful. When there is some sort of problem
with a driver, the missing compatible string (for example) may be the
cause.

The RPC HF might be locked by ATF, and any access to its register

The ATF should be patched to set RPC node status = "okay" in the DT

and that way U-Boot could access the RPC HF safely.

Add sysinfo node and phandle to the board ID EEPROM on all boards
where this functionality is described in DT, which is Salvator-X(S),
ULCB and Ebisu. The u-boot,dm-pre-reloc is necessary here, since the
sysinfo must be available early during boot. The V3M and V3H boards
currently do not describe this board ID EEPROM in upstream DT, but
that could be easily added later, once the DTs contain the necessary
nodes.

ULCB and Ebisu needs the full EEPROM node in the u-boot extras DT,
since the EEPROM node is still missing in the upstream DTs. Ebisu
also needs extra compatible string override for the i2c_dvfs.

U-Boot now supports parsing SPI NOR partitions from Device Tree. So enable
'mtd' command support for Espressobin board and define partition layout in
U-Boot Espressobin DTS file. Access to SPI NOR via 'sf' command is old
method and 'mtd' command is now preferred variant.

From include file remove '#define CONFIG_MTD_PARTITIONS' as this option is
now defined and enabled in defconfig file. This change is required to fix
compile error:
