In theory gsi base can start from 0 on loongarch virt machine, however gsi base is hard-coded in linux kernel loongarch system, else system fails to boot. This patch renames macro PCH_PIC_IRQ_OFFSET with VIRT_GSI_BASE, keeps value unchanged. GSI base is common concept in acpi spec and easy to understand.
