bsps/imxrt: Simplify linkcmds and make it flexible
Calling the memory FLASH and EXTRAM instead of FLEXSPI and SDRAM makes
it simpler to support other types of external RAM. This patch also
removes some of the calculations and improves names and documentation to
avoid pitfalls. It removes a unnecessary memory definition.
Update #4180
