From: Sean Wang <[email protected]>
Add cpufreq support to MT7622 SoC and also include some cleanups
with the generic naming to explicitly support all MediaTek SoCs.

cpufreq: mediatek: add cleanups with the more generic naming

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.

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".
