Thomas Richard 19d5619479 stm32: add STM32MP157C-DK2 support
Add STM32MP157C-DK2 support. This profile also supports the STM32MP157F-DK2
board. The only difference between these two boards is the CPU frequency
(650MHz for 157C and 800MHz for 157F).

A SCMI variant is available. With this variant the reset and clock
resources are provided by OP-TEE and the associated SCMI services.
It is the configuration recommended by STMicroelectronics, with secured
system resources.

The specifications bellow only list supported features.

Subject: [PATCH] net: stmmac: dwmac-stm32: update err status in case different
of stm32mp13
The mask parameter of syscfg property is mandatory for MP13 but
optional for all other cases.
The function should not return error code because for non-MP13
the missing syscfg phandle in DT is not considered an error.
So reset err to 0 in that case to support existing DTs without
syscfg phandle.
