Underscores should not be used in node names (dtc with W=2 warns about
them), so replace them with hyphens. This should have no impact on
known users: Linux MFD driver does not care about children node names.
DTS was already adjusted in commit 0f47ef3ff1 ("arm: dts: allwinner: drop
underscore in node names"), so without this change, we observe
dtbs_check warnings:
sun6i-a31s-colorfly-e708-q1.dtb: prcm@1f01400: 'ahb0-clk', 'apb0-clk', 'apb0-gates-clk', 'apb0-rst', 'ar100-clk', 'ir-clk' do not match any of the regexes: '^.*_(clk|rst)$', 'pinctrl-[0-9]+'
