This commit enables imx28 based XEA board's u-boot.sb (SPL) to download
u-boot proper (u-boot.img) via Ymodem protocol.

This is extremely useful in the recovery scenario where u-boot.sb is
downloaded via uuu utility to SDRAM [*], and then one can upload u-boot
proper via serial console to fully debrick the device.

Note - debricking procedure of imx28 devices:
- NXP's original USB based tools (like mxsldr or uuu) expect single
  u-boot.sb which is a relic of the old U-Boot (~2013) without SPL and
  U-Boot proper distinction.

[*] On Host:
------------
cat << EOF > imx28_xea.lst
uuu_version 1.3.0
SDPS: boot -f /srv/tftp/xea/u-boot.sb
SDPU: done
EOF

Please start picocom:
sudo picocom -b 115200 -s "sz -vv" /dev/ttyUSB1
sudo ./uuu/uuu -V imx28_xea.lst

On the U-boot console one shall see:
Trying to boot from UART
CCC

Then please press CTRL+A, S
and type u-boot.img

Current codes assume the OPTEE address is at the end of first DRAM bank.
Adjust the process to allow OPTEE in the middle of first bank.

When OPTEE memory is removed from first bank, it may split the first bank
to two banks, adjust the MMU table for the split case,
Since the default CONFIG_NR_DRAM_BANKS is 4, it is enough, just enlarge
i.MX8MP evk to default to avoid issue.

There are two options that are currently whitelisted, but they
are redundant, because there are not necessary since Kconfig options
exist to basically state the same thing.

CONFIG_DIRECT_NOR_BOOT and CONFIG_USE_NOR are both set together and
only used by the da850 when booting from NOR, however the only time
CONFIG_MTD_NOR_FLASH is configured is when booting from NOR. Since
NOR doesn't need SPL, the options for SPL can be moved to a check for
building SPL instead of checking for NOR.

This patch removes the checks for these two config options and unifies
the checks around the Kconfig option of CONFIG_MTD_NOR_FLASH.

Since this board is the only board that uses these two config options,
they can be removed from the whitelist table.

When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.
