Linux uses some kind of MFD scheme for the devices in the SLCR register
range, which involves adding the parent register base address to the
register offset of the child devices, as described in DT. This needs
non-standard code in each of those child device drivers.
Instead of replicating this weird driver code, fix up the SLCR parent
device DT ranges to do the translation.
