nds32: linker script: GCOV kernel may refers data in __exit
This patch is used to fix nds32 allmodconfig/allyesconfig build error
because GCOV kernel embeds counters in the kernel for each line
and a part of that embed in __exit text. So we need to keep the
EXIT_TEXT and EXIT_DATA if CONFIG_GCOV_KERNEL=y.
