Subject: [PATCH] nrf/Makefile: Disable ROM text compression when compiling for
 debug.

When compiling for debug (-O0) the .text segment cannot fit the flash
region when MICROPY_ROM_TEXT_COMPRESSION=1, because the compiler does not
optimise away the large if-else chain used to select the correct compressed
string.

This commit enforces MICROPY_ROM_TEXT_COMPRESSION=0 when compiling for
debug (DEBUG=1).
