security: Add memory subfolder
Add files to introduce a memory clearing framework. Introduce Kconfig PLATFORM_HAS_DRAM_CLEAR that is to be selected by platforms, that are able to clear all DRAM.
Introduce Kconfig SECURITY_CLEAR_DRAM_ON_REGULAR_BOOT that is user selectable to always clear DRAM on non S3 boot.
The function security_clear_dram_request tells the calling platform when to wipe all DRAM. Will be extended by TEE frameworks.
Add Documentation for the new security API.
