These basic tests are generic and should be used independently of the
driver, depending on the plaftorm characteristics.

stm32mp_ddrctl structure contains DDRCTRL registers definitions.
stm32mp_ddr_info contains general DDR information extracted from DT.
stm32mp_ddr_size moves to the generic side.
stm32mp1_ddr_priv contains platform private data.
stm32mp_ddr_dt_get_info() and stm32mp_ddr_dt_get_param() allow to
retrieve data from DT. They are located in new generic c/h files in

The support of a predefined DDR PHY tuning result is removed for
STM32MP1 driver because it is not needed at the supported frequency
when built-in calibration is executed.
The calibration parameters were provided in the device tree by the
optional node "st,phy-cal", activated in ddr helper file by the
compilation flag DDR_PHY_CAL_SKIP and filled with values generated
by CubeMX.
This patch
- updates the binding file to remove "st,phy-cal" support
- updates the device trees and remove the associated defines
- simplifies the STM32MP1 DDR driver and remove the support of
the optional "st,phy-cal"
After this patch the built-in calibration is always executed.

regulator_disable() and regulator_enable() was not checked.
If they fail, this means there is an issue either with PMIC or I2C.

When retrieving data from stm32 image file, the header is removed with
a memcpy that shifts the data to overwrite the useless header for next
binary.
STM32 binary from boot device:
|-------------------------------------|
| header | payload |
|-------------------------------------|
After the memcpy:
|-------------------------------------|
| payload | remain |
|-------------------------------------|
But the remaining data after the shifted payload is still in
the cache. As it is of no use for anyone, just invalidate the cache
at this address.
This is required if the DDR is mapped secure in BL2, and the secure
access is forbidden in BL33, or else TZC-400 issues an error.

Fixes implementation against build warning reported by GCC:
drivers/st/io/io_stm32image.c: In function ‘stm32image_partition_read’:
drivers/st/io/io_stm32image.c:249:6: error: ‘result’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
int result;
^~~~~~
Actually, by construction the current implementation of function
stm32image_partition_read() does not mandate result to be initialized
since it always reaches the exit point with a valid value in 'result'.
Yet, this change prevents compiler from complaining and is more robust
against future changes in the implementation.
