This is mostly a stub which completes SPI transactions as noops
by masking out the error interrupts and never clearing the IPCMDDONE
interrupt.
Although incomplete, this allows software that uses NXP's mcuxpresso
SDK to run the SDK board initialization functions.
It also supports AHB memory access, aka XIP, for now as simple RAM
memory regions.
The patch includes an automatically generated header which contains
the register layout and helpers.
The header can be regenerated with the svd-flexspi target when the
build is configured with --enable-mcux-soc-svd.
