2928b71a69 mips: Work around an issue with GCC 8.

d6220f618b MIPS: emulate -ffunction-sections with macros in mmu-mips 
Using a macro to put each function in its own .icode-based section
allows us to put the functions in IRAM _and_ have linker GC. This
removes a troublesome #ifdef BOOTLOADER_SPL on the X1000 target.

777f63d529 Move MIPS cache management functions to IRAM 
Previously these were placed in DRAM, which is overwritten by RoLo
when it loads a new image, but RoLo must call commit_discard_idcache()
after loading the image.

6a67707b5e Commit to certain names for cache coherency APIs and discard the aliases. 
Wouldn't surprise me a bit to get some non-green.
