ARM: 8310/1: l2c: Fix prefetch settings dt parsing
Allow prefetch settings overriding by device tree, in case
l2x0_cache_size_of_parse() returns value, prefetch tuning
properties are silently ignored. E.g. arm,double-linefill* and
arm,prefetch*.
This happens for example, when "cache-size" or "cache-sets"
properties haven't been filled in l2c dt node.
Comments from Fabrice Gasnier:
Allow device tree to override the L2C prefetch settings, even when
l2x0_cache_size_of_parse() fails to parse the cache geometry due to (eg)
missing "cache-size" or "cache-sets" properties.
