digilent_arty/CRG: Add with_rst parameter to be able to easily disable rst.
...
On Arty, cpu_rst pin is connected to a button but also to USB-UART which also
resets the SoC when USB-UART is connected which is in some case not wanted.
with_rst provides an easy way to disable rst by setting it to False.

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.
