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

On closed chips, it is not allowed to open debug. The BSEC debug
register can not be rewritten.
On open chips, the debug is already open, no need to rewrite this
register. This part of code is just removed.
An INFO message is displayed if debug is disabled.
The freeze of the watchdog during debug is also removed.
In case of debug, this must be managed by the software that enables
the debugger.

Correctly handle USB_DESC_TYPE_OTHER_SPEED_CONFIGURATION request
in USB driver and support a different result than
USB_DESC_TYPE_CONFIGURATION with the new optional ops
get_other_speed_config_desc().
The support of this descriptor is optionnal and is only
required when high-speed capable device which can operate at its
other possible speed.
This patch allows to remove the pbuf update in usb_core_get_desc()
and solves an issue on USB re-enumeration on STM32MP15 platform
as the result of get_config_desc() is a const array.
This issue is not see on normal use-case, as the USB enumeration
is only done in ROM code and TF-A reuse the same USB descritors.
