ac28e59a57 usb: Migrate to support live DT for some driver
Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

- the registers of the param 'phy.cal' are initialized to 0 when
  "st,phy-cal" is not present in device tree (default behavior when
  DDR_PHY_CAL_SKIP is not activated)
- the info 'cal' field can be use to change the calibration behavior
  - cal=1 => use param phy.cal to initialize the PHY, built-in training
             is skipped
  - cal=0 => param phy.cal is absent, built-in training is used (default)

This commit manages diversity for STM32M15x SOCs with:

  The differences between those SOCs are:
  -STM32MP151 [1]: common file.
  -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU.
  -STM32MP157 [3]: STM32MP153 + DSI + GPU.
- new files to manage security diversity on STM32MP15x SOCs.
  On STM32MP15xY, "Y" gives information:
  -Y = A means no cryp IP and no secure boot.
  -Y = C means cryp IP + secure boot.
- stm32mp157 pinctrl files to better manage package diversity.

888dc68136 board: stm32mp1: add finished good in board identifier OTP
Update the command stboard to support the updated coding of OTP 59 with
finished good.

The ST product codification have several element
- "Commercial Product Name" (CPN): type of product board (DKX, EVX)
  associated to the board ID "MBxxxx"
- "Finished Good" or "Finish Good" (FG):
  effective content of the product without chip STM32MP1 (LCD, Wifi, …)
- BOM: cost variant for same FG
  (for example, several provider of the same component)

For example
- commercial product = STM32MP157C-EV1
- Finished Good = EVA32MP157A1$AU1

Booth information are written on board and these information is also saved
in OTP59:

bit [31:16] (hex) => Board id, MBxxxx
bit [15:12] (dec) => Variant CPN (1....15)
bit [11:8]  (dec) => Revision board (index with A = 1, Z = 26)
bit [7:4]   (dec) => Variant FG : finished good (NEW)
bit [3:0]   (dec) => BOM (01, .... 255)

The updated command is:
  stboard [-y] <Board> <VarCPN> <Revision> <VarFG> <BOM>

And the displayed STMicroelectronics board identification is:
  Board: MB<Board> Var<VarCPN>.<VarFG> Rev.<Revision>-<BOM>

7ae22d7278 arm: stm32mp: bsec: add permanent lock support in bsec driver
Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver.
The write access only available for Trusted boot mode, based on new
SMC STM32_SMC_WRLOCK_OTP.

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

Read lock status of fuse 57 (0x39)

  STM32MP> fuse sense 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

Set permanent lock of fuse 57 (0x39)

  STM32MP> fuse prog 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

WARNING: the OTP lock is updated only after reboot

WARING: Programming lock or fuses is an irreversible operation!
        This may brick your system.
