From: Sean Wang <sean.wang@mediatek.com>

Add cpufreq support to MT7622 SoC and also include some cleanups
with the generic naming to explicitly support all MediaTek SoCs.

Subject[PATCH 1/2] cpufreq: mediatek: add cleanups with the more generic naming
Message-ID<ucwfL-5MY-9@gated-at.bofh.it>
In reply to#1707241
From: Sean Wang <sean.wang@mediatek.com>

Since more MediaTek SoCs can be supported with the cpufreq driver and not
limited to MT8173, a couple of cleanups are done here with renaming those
functions and related structures with "mtk" instead of "mt8173".

From: Sean Wang <sean.wang@mediatek.com>

MT7622 is a 64-bit ARMv8 based dual-core SoC (2 * Cortex-A53) with a
single cluster. The hardware is also compatible with the current driver,
so add MT7622 as one of the compatible string list.
