mainboard/google/reef: keep LPSS_UART2_TXD high in suspend state

The cr50 part on reef is connected to the SoC's UART lines. However,
    when the tx signal is low it causes an interrupt to fire on cr50.
    Therefore, keep the tx signal high in suspend state so that it doesn't
    cause an interrupt storm on cr50 which prevents cr50 from sleeping.

BUG=chrome-os-partner:63283
    BRANCH=reef
    TEST=s0ix no longer causes interrupt storm on cr50. Power consumption
         normal.
