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).

UART pin assignment
-------------------
The pin assignment of UARTs to pins is fixed.
The UARTs are numbered 0..8. The rx/tx pins are assigned according to the
tables below:

Legend:
* Qm/n: QTMR module m, channel n
* Fm/n/l: FLEXPWM module m, submodule n, channel l. The pulse at a X channel
is always aligned to the period start.
Pins without a PWM signal are not listed. A signal may be available at more
than one Pin. FlexPWM pins may also be pure CPU pin, not assigned to a board
signal. In that case the PWM output is disabled. The PWM channel of a submodule
0 may still be used as synchronization source for other channels of the same
module, unless used by another peripheral.

The SPI signals have fixed assignments to GPIO pins.
It depends on the board design, which SPI's signals are exposed to the user, as
detailed in the table below. The signal order in the table is: CS0, CS1, MOSI, MISO, CLK.
