devkit3250: add Timll DevKit3250 board initial support

This change adds a basic support for Embest/Timll DevKit3250 board, NOR and UART are the only supported peripherals for a moment. The board doesn't require low-level init, because the initial SDRAM and GPIO configuration is performed during kickstart bootloader execution.

Probably, it will be a good thing to drop the address part globally, as it can change and you may not be around to look for your files to change it.
