To manager MediaTek system clock reset easier, we move the driver to drivers/reset/mediatek. - Create reset/mediatek folder. - Move clk/mediatek/reset.c to reset/mediatek/reset-mediatek-sysclk.c - Because we don't want to build in unsed static variable, we use clk KConfig to separate them. For example, when we use MT8186, we don't want to build in the static constants for MT8195. - Move reset data which are scattered around the mediatek drivers to reset-mtxxxx.c. - There are two version for mtk_reset_init because some mediatek clock drivers (mt8135 and mt8173) are using device_node instead of device, so we need to add two version for the init function.
