armio.c: set GPIO2 output high initially On TI-canonical platforms GPIO2 is DCD modem control output. In TI's original code the AI_InitIOConfig() function called from Init_Target() would configure GPIO2 as an output and set the initial output value to low, but then the init code in uartfax.c called from Init_Serial_Flows() would immediately change it to high, corresponding to DCD not asserted. The result is a momentary asserted-state glitch on the DCD output. The present change eliminates this glitch, setting DCD output to not-asserted initially like it should be.
