bsps/imxrt: Fix OCRAM, ITCM and DTCM sizes
The sizes are configurable via fuses or per software via some registers.
At the moment the registers are not changed. Changing the registers
destroys data stored in the RAM areas (like application code or data).
So either the fuses or some bootloader should be used to set them before
the application starts.
This also adds an OCRAM only linker command file.
Update #4180
