hw/loongarch/virt: rename PCH_PIC_IRQ_OFFSET with VIRT_GSI_BASE

Browse source 
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.
