[PATCH 2/2] hw/misc/allwinner-h3-dramc: enforce 64-bit multiply when calculating row mirror address

The allwinner_h3_dramc_map_rows function simulates row addressing behavior when bootloader software attempts to detect the amount of available SDRAM. Currently the line that calculates the 64-bit address of the mirrored row uses a signed 32-bit multiply operation that in theory could result in the
