Refactors nxp i.mx, kinetis, and lpc board-level device trees to use
DT_SIZE_K and DT_SIZE_M macros to define external memory sizes. This is
self documenting and easier to read.

Sets the device tree chosen node for data tightly coupled memory (DTCM)
on i.mx rt boards that aren't already using DTCM as the chosen SRAM.
Leverages the common cortex-m linker section instead of the soc-specific
one.

Removes the DATA_LOCATION Kconfig symbol from the i.mx rt soc series and
refactors corresponding boards to use a device tree chosen node instead.
The external SDRAM is chosen on all boards that can support it;
otherwise the internal DTCM is chosen.

Have nodelabels match the SoC docs so when a nodelabel reference is
made in the code its easier to relate to the SoC.

Defines device tree aliases for on-chip peripherals at the soc level
instead of the board level for all i.mx rt socs. The eliminates some
duplicate code in the board level device trees, and will allow drivers
to use device-tree generated macros directly instead of through dts
fixups.
