[PATCH v6 05/12] hw/mem/cxl-type3: Refactor ct3_build_cdat_entries_for_mr to take mr size instead of mr as argument

[nifan.cxl@gmail.com]

From: Fan Ni <fan.ni@samsung.com>

The function ct3_build_cdat_entries_for_mr only uses size of the passed
memory region argument, refactor the function definition to make the passed
arguments more specific.
