Modified Files:
	src/sys/dev/hpc: hpf1275a_tty.c

Log Message:
If tty that we open already has hpf1275a line discipline set, don't
spawn new pseudo-device and wskbd instances.

XXX: The logic for exclusive use needs to be thought out better, but
for now this should at least prevent scores of new hpf1275a/wskbd
being attached if you accidentally set this line discipline on your
serial console.
