xlat_tables_v2: mark 'xlat_clean_dcache_range' unused
The armclang compiler can warn if a variable is declared but
is never referenced. The '__attribute__((unused))' attribute
informs the compiler to expect an unused variable, and tells
it not to issue a warning.
This patch marks the 'xlat_clean_dcache_range' function as
"unused" to fix this armclang compiler warning.
