fix(nxp-drivers): ddr: corrects mapping of HNFs nodes

Corrects mapping of HNFs nodes with SNFs nodes based on their
proximity in CCN508 ring when disabling unused ddr controller.

When DDRC 2 disabled and DDR 1 is active the mapping is 0x3/3/8/8/8/8/3/3.
When DDRC 1 is disabled and DDR2 is active the mapping is 0x
18/18/13/13/13/13/18/18 .
