[v2,1/3] macio: don't reference serial_hd() directly within the device

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
the setting of user_creatable to false accordingly.

Applied to ppc-for-5.2, thanks.

Ah okay, I was planning to send a separate qemu-macppc pull request myself with these 
patches plus some cherry-picks from Zoltan's patchset after some more testing. Does 
this mean you would prefer to take the patches directly yourself?


ATB,

Mark.

Not really.  I sent a PR recently, so I probably won't do another for
a little while.  So go ahead and send yours, and mine should rebase
easily enough.
