[PATCH 7/7] soc: mediatek: mtk-mmsys: Add resets for mt8167

[Luca Leonardo Scorcia]

The mt8167 SoC has 64 MMSYS resets, split in two contiguous 32-bits
registers, MMSYS_SW0_RST_B (0x140) and MMSYS_SW1_RST_B (0x144), as
also stated in the downstream kernel for the Lenovo Smart Clock
in the ddp_reg.h header.
