NRF52 serial: Fix UART console RX

While investigating the RX issue on NRF52_DK after SDK 14 updates,
it is observed that the RX FIFO doesn't get filled up when the
flow control is disabled. If using Serial interface, the stdio file
handles (0, 1, 2) get opened. This results in configuring the flow
control for STDIO.

However, if RawSerial is used, the STDIO file handles
don't get opened. During the debug process it was observed that if the
flow control is configured once and set to disabled the RX flow worked
as expected.

Alternative to this approach is for the user application specifically
enables flow control as done in mbed's Greentea test suite. See https://goo.gl/r8nBYH

See https://goo.gl/8VB2qg step 14 for _initio's description.
See test code to reproduce the issue and test fix here: https://goo.gl/AQU1xG
