The signal integrity test generates pattern on DDR lines
for certification. The signals must be as fast as possible
and unidirectional.
The test is required from our HW team. The available
u-boot memory test doesn't full fill the our requirements.
The test is planed to be used in all new siemens boards.

Add siemens specific memory test. Enable it through Kconfig option
SPL_CMT. The test is required from our HW team. It runs over
temperature during many days:
* must run indefinitively through the *whole* DDR area,
so we cannot use linux memtest for example.
* must write/read/check all values

We have many HW with capricorn i.MX8X boards. The difference in u-boot is
at all by the display of the LEDs.
* put upstream a reference project & board for DT and defconfig
* use the capricorn prefix outside the board/siemens/capricorn folder

- Provide a default Kconfig value of the default script
- Largely continue to define this via the board Kconfig file
- For the boards that select a script based on defconfig rather than
TARGET, keep this within the defconfig.
