66d7c8bf8e feat(stm32mp1-fdts): remove PLL1 settings
TF-A BL2 always boot at 650MHz using an algorithm to calculate PLL1
settings, without reading DT. Remove the corresponding nodes.

d594239d4e feat(stm32mp1-fdts): move RNG1 to CSI to improve random generation
LSI was too slow to provide enough random numbers (limited
to 6ms for 16 bytes production). Switch to CSI that allow
to get the RNG fifo ready in less than 50µs.

f0c19f252b refactor(stm32mp15-fdts): remove unused secure-status properties
For peripheral where both status and secure-status are set to okay,
the function fdt_get_status() returns the same status (DT_SHARED) if
secure-status property is omitted. This secure-status property can then
be removed in boards DT files for iwdg nodes.

0791aaf442 refactor(stm32mp15-fdts): remove RCC secure-status
The RCC security is managed with a dedicated compatible:
"st,stm32mp1-rcc-secure" [1].
Remove useless secure-status property in boards rcc nodes.

9eed71b722 fix(stm32mp1): fdts: stm32mp1: align DDR regulators with new driver
With recent changes, TF-A now panics on MC-1, Avenger96 and Odyssey:

  NOTICE:  CPU: STM32MP157C?? Rev.B
  NOTICE:  Model: Linux Automation MC-1 board
  ERROR:   regul ldo3: max value 750 is invalid
  PANIC at PC : 0x2ffeebb7

as the driver takes great offense at the content of the device
tree. The parts in question were copy-pasted from ST DTs, but
those ST DTs were fixed by commit 67d95409ba
("refactor(stm32mp1-fdts): update regulator description").

Fix the breakage by transplanting the same changes into all
remaining STM32MP1 DTs.

Change was boot-tested on MC-1, but only build tested for the
other two.

277d6af561 fdts: stm32mp1: realign device tree with kernel
There is one dtsi file per SoC version:
- STM32MP151: common part for all version, Single Cortex-A7
- STM32MP153: Dual Cortex-A7
- STM32MP157: + GPU and DSI, but not needed for TF-A

The STM32MP15xC include a cryptography peripheral, add it in a dedicated
file.

There are 4 packages available, for which  the IOs number change. Have one
file for each package. The 2 packages AB and AD are added.

STM32157A-DK1 and STM32MP157C-DK2 share most of their features, a common
dkx file is then created.

Some reordering is done in other files, and realign with kernel DT files.

The DDR files are generated with our internal tool, no changes in the
registers values.

2dc9fe70da fdts: stm32mp1: move FDCAN to PLL4_R
LTDC modifies the clock frequency to adapt it to the display. Such
frequency change is not detected by the FDCAN driver that instead
caches the value at probe and pretends to use it later.

This change fixes the issue by moving the FDCAN to PLL4_R,
leaving the LTDC alone on PLL4_Q.
