Enables Nordic Semiconductor flash driver for nRF RRAM controllers.
The entire contiguous block of RRAM gets logically divided into pages,
but partial erase is always supported.

Number of 128-bit words.
Maximum buffer size can be configured to the value of 32 (128-bit words).
Set 0 to disable write-buffer.

help
This is a multiplier that will be divided by 10 that is applied
to the flash erase and write operations timeout. The base for
the multiplication would allow erasing all nRF flash pages in
blocking mode.
