msm_serial_hs: Vote for clocks during tty close



While BT operation is in progress, it's possible for
client functions to explicitly turn off the
UART clocks without notifying TTY layer.  Then when
TTY layer try to access UART, L2 error happened because
of un-clocked registers.  Since there is no clear way
to notify clients to turn on clocks before TTY access
UART driver will implicilty turn on the clocks.
