* configs/lpc4330-xplorer/up_nsh.c: Add support for a basic SPIFI block
driver for use by NSH. Does not work! Crashes on first SPIFI write.
* configs/lpc4330-xplorer/*/defconfig: Calibrate delay loops (this is
based on the current "slow" 72MHz M4 clock and will need to be
re-calibrated when this is increased).
