Title: cc2538: Set the type of the .nrdata output section to NOLOAD

The .nrdata section is volatile, so its initialization must be controlled by the
application, and not be automatically done by the startup code. It should
neither be zeroed like .bss, nor be initialized from data in flash memory like
.data. This was already supposed to be the case, but the output section type of
.nrdata was not set to NOLOAD, causing the generated ELF .nrdata section header
to be of type PROGBITS instead of NOBITS, i.e. load data was generated to be
programmed in RAM, thus producing huge unprogrammable .bin files.
