targets: Remove spiflash mapping on targets where it's no longer useful.

arty: Switch SPI Flash rate to 1:2 (DDR) (Possible on Arty since SPI Flash's clk does not require use of STARTUPE2).
...
On the Digilent Arty, the SPI Flash's clk is connected to CCLK (that can be driven
through the STARTUPE2) but also to another generic IO that can be use to drive the
clock through DDR primitives.

targets/add_sdram: Simplify call by removing useless arguments.
...
- main_ram mem_map is now directly used by add_sdram when origin is None.
- max_sdram_size/min_l2_data_width are no longer exposed as targets arguments this can
still be used enforced directly in the few cases it is useful.

boards: Add Vendor prefix to platforms/targets name when useful and when multiple boards from the same vendor. (With Retro-Compat on the imports).
