[PATCH] hw/loongarch/virt: Replace RSDT with XSDT table

[Bibo Mao]

XSDT table is introduced in ACPI Specification 5.0, it supports 64-bit
address in the table. There is LoongArch system support from ACPI
Specification 6.4 and later, XSDT is supported by LoongArch system.

Here replace RSDT with XSDT table.
