Stephen Rothwell d86d9b8cab [POWERPC] fix spin lock nesting in hvc_iseries
We had nested spinlocks using the same flags variable, but it turns out
that we don't need the nested locks at all (the lock protects a static
buffer that we aren't using here), so just remove the extra locks.

Spotted by Alexey Dobriyan.

Stephen Rothwell de0138da0f [POWERPC] The two vio HVC backends clash
Make sure only one of them actually registers as a driver.

Also, remove cast from get_property().

Stephen Rothwell 4e9e95a355 [POWERPC] Make the hvc_console output buffer size settable
So the iSeries console will be faster since it can send up to 200 bytes at
a time to the Hypervisor.  This only affects the tty part of the console,
the console writes are still in 16 byte lots.

Stephen Rothwell 8bff05b052 [POWERPC] iseries: A new iSeries console
This driver uses the hvc_console.c infrastructure that is used by the
pSeries virtual and RTAS consoles.  This will allow us to make viocons.c
obsolete and is another step along the way to a combined kernel (as
viocons could not coexist with CONFIG_VT).
