In addition to nearest upstream bridge, driver may want to know if the
entire hierarchy can be powered off to perform different action.
So walk higher up the hierarchy to find out if any device has valid
_PR3.
The user will be introduced in next patch.

Cancel the do_wakeup flag in hvc_struct, and change it to immediately
wake up tty when hp->n_outbuf is 0 in hvc_push().
When we receive a key input character, the interrupt handling function
hvc_handle_interrupt() will be executed, and the echo thread
flush_to_ldisc() will be added
