* GPIO: On STM32MP13, there are no banks GPIOJ, GPIOK and GPIOZ.
* STM32MP13 is a single Cortex-A7 CPU: remove reset from MPU1
and reset from MCU traces
* There is no MCU on STM32MP13. Put MCU security management
under STM32MP15 flag.
* The authentication feature is not supported yet on STM32MP13,
put the code under SPM32MP15 flag.
* On STM32MP13, the monotonic counter is managed in ROM code, keep
the monotonic counter update just for STM32MP15.
* SYSCFG: put registers not present on STM32MP13 under STM32MP15
flag, as the code that manages them.
* PMIC: use ldo3 during DDR configuration only for STM32MP15
* Reset UART pins on USB boot is no more required.

Use dt_find_otp_name() to retrieve platform OTP information
from device tree, directly or through stm32_get_otp_index() and
stm32_get_otp_value() platform services.
String definitions replace hard-coded values, they are used to call
this new function.

This new function is used to fill the register(s) responsible to enable
high speed mode for pad in low voltage (<2.7V).

Add enable_io_comp_cell and disable_io_comp_cell local helpers
to enable or disable an IO compensation cell.

Use the clock framework functions in SYSCFG driver instead of dedicated
functions.

Use a timeout during IO compensation enable function, when
waiting for ready status. If timeout expires, print a warning
message, to indicate that the SoC recommendation is not followed.

In stm32mp1_syscfg_disable_io_compensation(), to disable the IO
compensation cell, we have to set the corresponding bit in
SYSCFG_CMPENCLRR register, instead of clearing the bit in SETR register.

Retrieve peripheral base address from a define instead of
parsing the device tree. The goal is to improve execution time.

The system configuration controller is mainly used to manage
the compensation cell and other IOs and system related settings.
The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.
Device tree files are also updated to manage vdd-supply regulator.
