Subject: [PATCH 4/9] memory: mtk-smi: Rename smi_gen to smi_type

This is a preparing patch for adding smi sub common.

About the previou smi_gen, we have gen1/gen2 that stand for the generation
number for HW. I plan to add a new type(sub_common), then the "gen" is not
prober. this patch only change it to "type", No functional change.
