mimxrt1011: Only re-init SPI when it's actually needed
...
If some crazy code (*cough* FourWire) decides to reconfigure the bus
before every transfer, it might get a bit slow...

Refine iMX RT memory layout and add three boards
...
Introduces a way to place CircuitPython code and data into
tightly coupled memory (TCM) which is accessible by the CPU in a
single cycle. It also frees up room in the corresponding cache for
intermittent data. Loading from external flash is slow!
The data cache is also now enabled.
Adds support for the iMX RT 1021 chip. Adds three new boards:
* iMX RT 1020 EVK
* iMX RT 1060 EVK
* Teensy 4.0
Related to #2492 , #2472 and #2477 . Fixes #2475 .
