Enable HW PWM driver instead of the SW one on nRF SoCs where the PWM
peripheral is present.
Default PWM instances are also enabled on Nordic DK boards so that it
is possible to build the basic fade_led sample for them without extra
adjustments.
After the above changes are applied, some configuration alterations
in basic samples blink_led and fade_led become no longer needed.
These are removed. And the blink_led sample is corrected so that it
works with the nRF HW PWM driver as well.

Correct it so that it is possible to use PWMs on nRF9160 as well,
not only on nRF5 family SoCs.

When the PWM_NRFX Kconfig option is enabled, add the nrfx driver
to the build automatically by selecting the NRFX_PWM option (it is
a hidden one, so the user cannot do it manually via menuconfig).

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Adds a translation layer to make the nrfx driver for nrf52 PWM
peripheral accessible via the Zephyr's API.
