MIPS: add compile time definition of L2 cache size
If configuration is set to skip low level init, automatic
probe of L2 cache size is not performed and the size is set to 0.
Flushing or invalidating the L2 cache will fail in this case.
Add a static configuration (SYS_DCACHE_LINE_SIZE) with default set to 0.
