FAO Arnd, Mark,
> Some platforms need to get system controller
> ready as soon as possible.
> The patch provides early_syscon_initialization
> which create early mapping for all syscon compatible
> devices in early_syscon_probe.
> Regmap is get via syscon_early_regmap_lookup_by_phandle()
> Regular device probes attach device to regmap
> via regmap_attach_dev().
> For early syscon initialization is necessary to extend
> struct syscon and provide remove function
> which unmap all early init structures.
