arm: SC598-SOM-EZKIT initial support

Browse Source 
Adds support for Analog Devices' SC598-SOM-EZKIT board. Includes:
- CONFIG options common to all SC5xx SoCs
- SoC specific configs in mach-sc5xx/Kconfig
- SPL config options in common/spl/Kconfig
- Memory Map for SPL
- Necessary board-specific init functions
- Board-specific Kconfig and environment in board/adi/
- Memory configuration
