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)

.. and set the "MasterPcsContinuous" flag, which removes some of the
gap between bytes of a single SPI transaction

mimxrt10xx: busio: cap SPI baudrate at 30MHz per datasheet2021-03-26T15:01:53+00:00Jeff Eplerjepler@unpythonic.net2021-03-25T18:37:37+00:00urn:sha1:9e110f120a323eff9989463771d8ea8ece6e8906mimxrt: SPI: Set the TCR value returned by MasterBaudSetRate2021-03-24T18:33:21+00:00Jeff Eplerjepler@unpythonic.net2021-03-24T18:07:07+00:00urn:sha1:b440883fe55666d12f94a6d48513a1a68d218bc4
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.
