MIPS: fix mips_cache fallback without __builtin_mips_cache
The "R" constraint supplies the address of an variable in a register. Use "r" instead and adjust asm to supply the content of addr in a register instead. Fixes: 2b8bcc5a ("MIPS: avoid .set ISA for cache operations") Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> Cc: Paul Burton <paul.burton@imgtec.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
