hw/omap: Fix default setup for OMAP UART devices
Character devices created by qemu_chr_open don't
allow duplicate device names, so naming all
UART devices "null" no longer works.
Running "qemu-system-arm -M n800" (and some other machines)
results in this error message:
qemu-system-arm: Duplicate ID 'null' for chardev
Can't create serial device, empty char device
This is fixed by setting a default label "uart1",
"uart2" or "uart3".
