[PATCH 7/8] memory: mtk-smi: Rearrange some function position alphabetically

From: Yong Wu
Date: Fri Aug 11 2017 - 05:57:39 EST

Only adjust some code position in Soc numerical order, from mt2701,
mt2712 to mt8173.

Besides, 3 minor changes:
1) fix a coding style issue:
CHECK: Alignment should match open parenthesis
+ writel(reg_val,
+ common->smi_ao_base
2) change from readl to readl_relaxed in gen1_config_port.
3) change the type "larbid" from "int" to "unsigned int" to meet
the requirement of of_property_read_u32.
