samd/Flash: Add the QSPI flash driver and the mpconfigboard.h files.

robert-hh · robert-hh · commit 2a2b6987af98 · 2023-06-05T08:45:10.000+02:00
The QSPI driver provides the interface for using an on-board QSPI
flash for the file system. It provides the same methods as the driver
for the internal flash and uses the same name. Therefore,only one of
the drivers for internal flash, SPI flash and QSPI flash must be
enabled at a time.
