powerpc/fadump: Annotate endianness cast with __force
Sparse reports an endianness error with the else case of
val = (cpu_endian ? be64_to_cpu(reg_entry->reg_val) :
(u64)(reg_entry->reg_val));
This is a safe operation because the code is explicitly working with
dynamic endianness, so add the __force annotation to tell Sparse to
ignore it.
