nds32: enable GCC LTO
- We have more flash space to use with nds32 toolchain GCC6.3.0,
so we enable a few console commands that were disabled previously.
And we also enable LTO to reduce the size of FW image.
- Put "__wait_evt" function into ram_code section to
fill the gap of flash and improving performance of code-fetch.
BUG=none
BRANCH=none
TEST=boot to kernel on reef_it8320.
