devkit3250: add Timll DevKit3250 board initial support

Browse source 
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.
