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.
