[PATCH 3/3] MIPS: sc-mips: L2 cache is inclusive of L1 dcache for CM3

[Paul Burton <paul.burton@xxxxxxxxxx>]

In systems with CM3 & higher, the L2 cache is inclusive of the L1
dcache. Indicate this such that cpu_has_inclusive_pcaches evaluates true
& we avoid some unnecessary cache ops during DMA cache maintenance.
