[PATCH v3 phy-next 1/8] soc: fsl: guts: use a macro to encode the DCFG CCSR space

From: Ioana Ciornei <ioana.ciornei@nxp.com>

Instead of using a hardcoded value when iomapping the DCFG CCSR space,
add a new macro for it. The code will be easier to follow this way,
especially when we add support for the DCFG DCSR space as well.
