EDAC/synopsys: Fix error injection on Zynq UltraScale+

EDAC/synopsys: Fix error injection on Zynq UltraScale+

The Zynq UltraScale+ MPSoC DDR has a disjoint memory from 2GB to 32GB.
The DDR host interface has a contiguous memory so while injecting
errors, the driver should remove the hole else the injection fails as
the address translation is incorrect.

Introduce a get_mem_info() function pointer and set it for Zynq
UltraScale+ platform to return host address.
