soc: Add the MAX32657 SoC

MAX32657 is Cortex-M33 based Analog Devices MCU.
It supports ARM TrustZone security model.
There will be two boards of this MCU Secure and Non-Secure

This commit defines Secure version of peripherals.

Basic feature of MAX32657 device:
- Core is Cortex-M33
- 50MHz IPO clock
- There are 54 interrupt vectors
- 1MB flash & 256 SRAM
- MAX32657 has:
   - 1 x UART
   - 1 x I2C/I3C
   - 1 x SPI
   - 6 x TIMER
   - 1 x RTC
   - 1 x WDT
