ACPI: Record Generic Error Status Block(GESB) table

Browse source 
kvm_arch_on_sigbus_vcpu() error injection uses source_id as
index in etc/hardware_errors to find out Error Status Data
Block entry corresponding to error source. So supported source_id
values should be assigned here and not be changed afterwards to
make sure that guest will write error into expected Error Status
Data Block.

Before QEMU writes a new error to ACPI table, it will check whether
previous error has been acknowledged. If not acknowledged, the new
errors will be ignored and not be recorded. For the errors section
type, QEMU simulate it to memory section error.
