[PATCH 5/6] macio: don't reference serial_hd() directly within the device

[Mark Cave-Ayland]

Instead use qdev_prop_set_chr() to configure the ESCC serial chardevs at the
Mac Old World and New World machine level.

Also remove the now obsolete comment referring to the use of serial_hd() and
change user_createable to true accordingly.
