231cb1ffd9 mimxrt10xx: Use the proper "betweenTransferDelay" (et al) values 
Set the betweenTransferDelay to the SCK low-time, to avoid long pauses
between bytes (transfers) while preventing the last SCK cycle in a byte
from being a runt pulse.

Compared to an earlier revision of this change, which just set the delays
all to zero, this doesn't break using an AirLift, which was sensitive
to the runt pulses (the simple loopback-wire test didn't detect the problem)

9e110f120a mimxrt10xx: busio: cap SPI baudrate at 30MHz per datasheet 2021-03-26 10:01:53 -05:00

b440883fe5 mimxrt: SPI: Set the TCR value returned by MasterBaudSetRate 
without this, the baud rate could be wrong; in my testing, it was
low by a factor of 2 when requesating baudrate=1_000_000 (1MHz).

When passing the baudrate in to LPSPI_MasterInit, the setting is made
automatically, but LPSPI_MAster_SetBaudRate just returns it via the
out-parameter tcrPrescaleValue.

Split pulseio.PWMOut into pwmio 
This gives us better granularity when implementing new ports because
PWMOut is commonly implemented before PulseIn and PulseOut.

dddd25a776 Combine similar strings to reduce size of translations 
This is a slight trade-off with code size, in places where a "_varg"
mp_raise variant is now used.  The net savings on trinket_m0 is
just 32 bytes.

It also means that the translation will include the original English
text, and cannot be translated.  These are usually names of Python
types such as int, set, or dict or special values such as "inf" or
"Nan".
