[PATCH 1/7] lib: utils/cache: fix andes_llcache_enable() return value

[Ben Zong-You Xie]

The driver returned 1 on success where callers expect 0, so the suspend
to RAM aborted right after disabling the LLC and before flushing it.

Fixes: 82b0961821e4 ("lib: utils/cache: add Andes last level cache controller")
