Subject: [PATCH v2] soc: mediatek: mmsys: Add sw0_rst_offset for MT8192

MT8192 has the same sw0 reset offset as MT8186: add the parameter
to be able to use mmsys as a reset controller for managing at
least the DSI reset line.

Signed-off-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

v2: Change the offset to 0x160 (as defined for MT8186). Thanks, Rex-BC!
