The previous commit removed the single use of instance
setting the "endianness" property.
Since classes can register their io_ops with correct
endianness, no need to support different ones.
Remove the code related to SDHCIState::endianess field.
Remove the now unused SDHCIState::io_ops field, since we
directly use the class one.
