Typo in linker.ld for NXP i.MX RT

[arvid-r]

Describe the bug
There is a typo in linker.ld for NXP i.MX RT platform since the conversion to new Devicetree macros. The start adress macro is used instead of the size macro for the ITCM and DTCM sections, which renders very large sections for these memories.

To Reproduce
Steps to reproduce the behavior:

1. cd samples/hello_world
2. mkdir build; cd build
3. west build -b mimxrt_1020evk
4. See output

Environment (please complete the following information):
MacOS and gnu toolchain, but should be the same for all OSs I guess

Easy fix. I will prepare a PR if no-one else does.
