I2C pinmap and HAL fixes for MIMXRT

[multiplemonomials]

Summary of changes

• All missing I2C pin mappings added to the pin map table, enabling any and all MIMXRT105x I2C pins to be used
• Fixed timing issue where the transactional API would not detect a NACK in the address byte, making it look like the slave acknowledged when it didn't

Impact of changes

This should fix some issues initializing and using I2C on the MIMXRT. In particular, the pins labeled as I2C on the Teensy should now be usable.

Note: Unfortunately, NACKs in address bytes are still not detected using the single-byte I2C API, and I'm not sure that this is possible to fix (the hardware seems to just wait a long time before sending the NACK flag).

I ran the I2C test suite with the test shield and it passed except for the full-chip EEPROM test (infinite hang) and the single-byte incorrect address test. I will look into those later...

@wwatson4506 Have you had a chance to look at this one?

Sorry, some how I missed this one...
