Subject: [PATCH] MIPS: SNI: Fix MIPS_L1_CACHE_SHIFT

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>")
