robert-hh 1074c784b0 mimxrt: Add support for Hyperflash chips. 
Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and
MIMXRT1064_EVK boards.

This commit includes:
- add support for Hyperflash
- modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to
  hyperflash.
- minor incidental changes to other boards so they still build

Note: Erasing a sector on the hyperflash is slow. It takes about a second,
which seems too long, but matches the data sheet.

robert-hh 53fea8598e mimxrt/boards: Add board configuration files for Teensy 4.1. 
These are at the moment more or less identical to the Teensy 4.0 files,
except for the pins.csv file and the flash size.
