* 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).
* configs/stm3220g-eval/include/board.h and configs/stm3240g-eval/include/board.h:
The SDIOCLK frequency in the F2 and F4 derives for PLL48CLK and not HCLK
so that the SDIOCLK input frequency should always be 48MHz.
