To manager mediatek system clock reset easier, we move the driver to
drivers/reset.
- 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 (For example,
if we use mt8186, we don't want to build in the variable of MT8195.),
we use clk KConfig to do this.
- Move reset data which are scattered around the mediatek drivers to
reset-mtxxxx.h.
- For mtk clk drivers which support device, we can ues
mtk_reset_controller_register() to register reset controller using
auxiliary bus.
- For mtk clk drivers which do not support device (only support
device_node), we use mtk_reset_{init/remove}_with_node to register
reset controller.

Changes for v4:
1. Rebased oo linux-next-1004.
2. Move reset data which are scattered around the mediatek drivers to reset-mtxxxx.h.
3. Add reset data of mt6795.
