powerpc/udbg: Remove unused udbg_read() The last user of udbg_read() was removed in 2005, in commit fca5dcd "Simplify and clean up the xmon terminal I/O". Given we haven't needed it for 7 years we can probably drop it. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
