[PATCH v1 05/22] hw/misc/aspeed_hace: Introduce 64-bit digest_addr variable for AST2700

[Jamin Lin via <qemu-devel@nongnu.org>]

The AST2700 CPU, based on the Cortex-A35, is a 64-bit processor with a 64-bit
DRAM address space. To support future AST2700 updates, a new "digest_addr"
variable is introduced with a 64-bit data type.
