TF-A BL2 always boot at 650MHz using an algorithm to calculate PLL1
settings, without reading DT. Remove the corresponding nodes.

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.

This is something commonly asked by Linux kernel DT maintainers [1].
The mentioned doc is not upstreamed, but may be checked with dtbs_check.
While at it align some nodes with Linux or OP-TEE.

The RCC security is managed with a dedicated compatible:
"st,stm32mp1-rcc-secure" [1].
Remove useless secure-status property in boards rcc nodes.

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.

Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the
STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a
cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a
4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD
output, and the other available at the MPU’s port PG3. The SoM can be
plugged into a carrier board using its three 70‑pin connectors.
Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in
a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a
microSD card port and various I/O interfaces.
The device tree is based on the DKx boards. TF‑A was successfully tested
on the board with Buildroot 2021.02 and U-Boot 2021.04.
