George G. Davis 3689a0ec60 [PATCH] serial: make sure UART is powered up when dumping MCTRL status 
Since serial devices are powered down when not in use and some of those
devices cannot be accessed when powered down, we need to enable power
around calls to get_mcrtl() when dumping port state via uart_line_info().
This resolves hangs observed on some machines while reading serial device
registers when a port is powered off.
