description:
Do not add PAPR vterm and /vdevice nodes if not configed
If the PAPR vterm hcalls are not supported then make sure they are not
in the devtree so Dom0 does not instantiate the vterm driver.
Sorry, I meant to mention this yesterday on-list... I've removed the
"nonblocking serial_getc" hack from Xen, which broke H_GET_TERM_CHAR
support. However, the normal Xen console driver (which hijacks
/dev/ttyS0, at least in dom0) is working fine for both input and
output. So make sure you aren't using /dev/hvc0 for domain console
output or a getty.

I don't object to these changes, but they are not all related to
vterms. Let's try to keep our changesets clean, please.
