arc: Eliminate unused code and data with GCC's garbage collector
Finally GCC's garbage collector works on ARC so let's use it.
That's what I may see for HSDK:
Before:
text data bss dec hex filename
290153 10068 222616 522837 7fa55 u-boot
After:
text data bss dec hex filename
261999 9460 222360 493819 788fb u-boot
Overall ~5% of memory footprint saved.
