ASoC: wcd_cpe_core: Fix address and size for ramdumps

Since the underlying codec can have different memory map, it is possible
the starting offset and size for DRAM can be different as well. This
causes the collected dumps to be incorrect on some platforms. Fix the
ramdump collection to obtain DRAM offset and size from CPE services
which is aware of the codec being used.
