nrf: Add support for floating point on nrf52 targets.

Duplicating pattern for detecting location of libm, libc and libgcc
from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
and adding libs into the compile. For nrf51 targets it is still set to
NONE as code grows to much (about 30k).

Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

nrf51:
======

without float support:
   text	   data	    bss	    dec	    hex	filename

with float support:

nrf: Use the name MicroPython consistently in comments

There were several different spellings of MicroPython present in comments,
when there should be only one.

Aligning to upstream commit 55f33240f3.
