Daniel Golle 9599a85dc2 mediatek: sync cpufreq support with changed compatible string
The compatible string for the MediaTek MT7988 SoC ended up being
'mediatek,mt7988a' instead of 'mediatek,mt7988' in the now upstream
dtsi. Adapt the cpufreq driver so support for frequency scaling is
again usable.

Subject: [PATCH] cpufreq: mediatek: Add support for MT7988A

From: Sam Shih <sam.shih@mediatek.com>
This add cpufreq support for mediatek MT7988A SoC.
The platform data of MT7988A is different from previous MediaTek SoCs,
so we add a new compatible and platform data for it.
