I was testing this on AM335x and realized that this leads to creation of two
'wakeup' entries for UART. One is created by the tty layer in serial-core.c
and the other is created here.

Here's what I see on a branch based on Tony's 3.2-rc6:

./sys/devices/platform/omap/omap_uart.0/power/wakeup
./sys/devices/platform/omap/omap_uart.0/tty/ttyO0/power/wakeup

Shouldn't the OMAP serial just enable the 'wakeup' entry created by serial-core.c?
