soc: mediatek: mtk-svs: Add a map to retrieve fused values

In preparation for adding a common efuse parsing function which will
greatly reduce code duplication, add a SoC-specific mapping that will
be used to retrieve the right SVS calibration values from the fuses.
The maps are two: one is a Global Map used for reading parameters that
are SVS-global, and one is a Bank Map for reading calibrations for
each SVS Bank.

While at it, also populate the map in the platform data for each SoC.

Being this a preparation commit, there are no functional changes.
