powerpc: Rewrite 4xx flush_cache_instruction() in C
Nothing prevents flush_cache_instruction() from being writen in C. Do it to improve readability and maintainability. This function is very small and isn't called from assembly, make it static inline in asm/cacheflush.h Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/93d93fc69b4b3ad3ceba2fc0756333c0c0245bb7.1597384512.git.christophe.leroy@csgroup.eu
