The current driver contains assembly code which is specific for the nRF51
SOC which makes it incompatible with other SOC's. This patch adds support
for other nRF SOC's as well. The timing is calucated based on the CPU clock
frequency, but can be configured manually as well if needed.
Changes have been verified on a Adafruit Feather nRF52840 Express board,
which contains a single NeoPixel RGB LED. Timings have been verified using
a scope connected to the WS1812 data line.

folder helps keep things tidy and lays the groundwork for further
improvements in the way samples are showing up in the docs.

There are several esp32-based boards that its conf and overlay
files are missing proper renaming to match cpu cluster.
This also removes all _SOC_ name from files.
