pmac_zilog,kdb: Fix console poll hook to return instead of loop
commit 38f8eefccf3a23c4058a570fa2938a4f553cf8e0 upstream.
kdb <-> kgdb transitioning does not work properly with this UART
driver because the get character routine loops indefinitely as opposed
to returning NO_POLL_CHAR per the expectation of the KDB I/O driver
API.
The symptom is a kernel hang when trying to switch debug modes.
