cache: sifive_ccache: Silence unused variable warning

With W=1 and CONFIG_RISCV_NONSTANDARD_CACHE_OPS=n, GCC warns:

drivers/cache/sifive_ccache.c: In function 'sifive_ccache_init':
drivers/cache/sifive_ccache.c:293:23: warning: variable 'quirks' set but not used [-Wunused-but-set-variable]
  293 |         unsigned long quirks;
      |                       ^~~~~~

This is expected, since QUIRK_NONSTANDARD_CACHE_OPS is the only quirk
still handled in this function.
