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.

lattice_crosslink_nx_evn: don't set MASTER_SPI_PORT=SERIAL
...
Setting MASTER_SPI_PORT=SERIAL causes the SPI flash pins to be reserved
for use by the sysCONFIG logic, and prevents user logic from assigning
them. This made it impossible to have a Litex design which accesses the
SPI flash on this board.
Remove the setting, so that we get the default behaviour which permits
user logic to assign these pins. In the unlikely event that someone
needs the pins to stay reserved for sysCONFIG after configuration (I'm
not sure why this would be needed) they could explicitly add this
command in their design.

```
Tip: Use `GTKTerm` to connect to /dev/ttyUSB0 (usually) and interact
with the LiteX BIOS.

FIX: OrangeCrab Feather SPI pad name
...
**Problems**
`SPIMaster` pad names are `clk`, `cs_n`, `mosi`, and `miso`.
However, `feather_spi` is using `sck` instead of `clk`, therefore
it is not able to use as-is for `SPIMaster`, for example,
with `add_spi` on Linux On LiteX VexRiscv.
**Solution**
In fact, `spisdcard` and other SPI related pad names are
using `clk`, only `feather_spi` is using `sck`.
Therefore, rename `sck` to `clk`.

lattice_crosslink_nx_evn: allow specifying the FPGA device
...
This board is documented as having the LIFCL-40-9BG400C part, but some
versions of the board exist which were fitted with LIFCL-40-8BG400CES,
an engineering sample part. The distinction is important because the
engineering sample requires a different device ID to be embedded in the
bitstream. If you try to build a bitstream for LIFCL-40-9BG400C and load
it onto LIFCL-40-8BG400CES the configuration fails (indicated by the red
"INITN" LED on this board).
Accept --device to allow the user to specify which FPGA part their board
has.
