nrf52 sys module does not have stdin,stdout or stderr

[jerryneedell]

This is related to the AMPY issue
scientifichackers/ampy#47

the atmel samd and esp8266 builds have sys.stdout implmented, but the nrf52 build does not and tehampy "get" function fails since it relies on sys.stdout.

I noticed that some key items are not enable in the nrf mpconfigport.h

nrf mpconfigport.h

#define MICROPY_PY_SYS_STDFILES                  (0)
#define MICROPY_PY_SYS_STDIO_BUFFER              (0)

#define MICROPY_PY_IO                            (0)
#define MICROPY_PY_IO_FILEIO                     (0)

esp8266 mpconfigport.h

#define MICROPY_PY_IO               (1)
#define MICROPY_PY_IO_FILEIO        (1)

#define MICROPY_PY_SYS_STDFILES     (1)
#define MICROPY_PY_SYS_STDIO_BUFFER (1)

I tried enabling these, but the build failed:

perhaps I missed some or there is some code missing from the nrf port. - I have not looked deeper yet.
