clk: mediatek: reset: Add infra_ao reset support for MT8192/MT8195

The infra_ao reset is needed for MT8192 and MT8195.
- Add mtk_clk_rst_desc for MT8192 and MT8195
- Add register reset controller function for MT8192 infra_ao.
- Move definition of infra reset from cl-mt8183.c to reset.h
  because it's the same definition with MT8192 and MT8195.
- Add new definition of infra reset_4 for MT8192 and MT8195.
- Add infra_ao_idx_map for MT8192 and MT8195.
