[PATCH 4/9] rockchip: rk3568: Remove unneeded syscon driver

Modern Rockchip device drivers use syscon_regmap_lookup_by_phandle()
to get a regmap or use a constant to get the fixed base address.

Remove the unneeded RK3568 syscon driver to discourage new uses of
syscon_get_regmap_by_driver_data() or syscon_get_first_range().

The generic_syscon driver will instead be used for the compatible
previously matched by the now removed driver.
