Fix HAL_UARTModemControl

Detail:
  s/UART:
  - HAL_UARTModemControl now uses the correct AND mask; previous code would have always had bit 0 of the mask set.
  - Fixed code in HAL_UARTModemControl that was testing for calls that don't update the register
Admin:
  Builds, but untested
  Identical fix was tested in OMAP3 HAL
