Add einjv2 extension struct and EINJv2 error types to prepare
the driver for EINJv2 support. ACPI specifications(1) enables
EINJv2 by extending set_error_type_with_address struct.

__counted_by marking seems appropriate here.

I understand __counted_by may seem appropriate here, however, component_arr_count
is a value set be the user and does not represent syndrome_array size.
The size of syndrome_array will be calculated in Patch 8/9.
