[ Upstream commit 564c836fd945a94b5dd46597d6b7adb464092650 ]

Commit 930beb5ac09a ("MIPS: introduce MIPS_L1_CACHE_SHIFT_<N>") forgot
to select the correct MIPS_L1_CACHE_SHIFT for SNI RM. This breaks non
coherent DMA because of a wrong allocation alignment.

Fixes: 930beb5ac09a ("MIPS: introduce MIPS_L1_CACHE_SHIFT_<N>")
