robert-hh 0f048a5a2a mimxrt/machine_spi: Allow a setting of -1 for cs in the constructor.
In that case, no Pin will be configured for the CS signal, even if it is
internally still generated.  That setting allows to use any pin for CS,
which then must be controlled by the Python script.

Also make the default cs=-1 to match other ports (software CS).
