Subject: [PATCH v1 08/20] soc: mediatek: mtk-svs: Add SVS-Thermal coefficient to SoC platform data

In preparation for commonizing the efuse parsing function, add the
SVS-Thermal coefficients for all SoCs for which said function can be
commonized (MT8186, MT8188, MT8192, MT8195) and assign those to their
platform data structure.
That will be used to calculate the MTS parameter with the equation
                     MTS = (ts_coeff * 2) / 1000

This commit brings no functional changes.
