The platform driver is dead code. It is not used by DT platforms since
commit bdb0066df96e ("mfd: syscon: Decouple syscon interface from
platform devices") which said:

    For non-DT based platforms, this patch keeps syscon platform driver
    structure so that syscon can be probed and such non-DT based drivers
    can use syscon_regmap_lookup_by_pdev API and access regmap handles.
    Once all users of "syscon_regmap_lookup_by_pdev" migrated to DT based,
    we can completely remove platform driver of syscon, and keep only helper
    functions to get regmap handles.

The last user of syscon_regmap_lookup_by_pdevname() was removed in 2018.
syscon_regmap_lookup_by_pdevname() was then removed in 2019, but that
commit failed to remove the rest of the platform driver.
