During msa311 accel IIO driver development

Andy requested to use proper units in the hz->ms calculation. Current
units.h header doesn't have milli, micro and nano HZ coefficients, so
some drivers (in the IIO subsystem) implement their own copies for that.

The current patchset resolves such a problem and intoduces general
MILLIHZ_PER_HZ, MICROHZ_PER_HZ and NANOHZ_PER_HZ definitions in the units.h,
and fixes all drivers which duplicate these units.

Changes:
* v2->v3:
- changed UHZ_PER_HZ to MICROHZ_PER_HZ and NHZ_PER_HZ to
NANOHZ_PER_HZ to save name consistency for all new HZ units

* v1->v2:
- changed MHZ_PER_HZ to a different name as Andy suggested
(suppose MILLIHZ_PER_HZ is good enough)

Dmitry Rokosov (3):
units: complement the set of Hz units
iio: accel: adxl345: use HZ macro from units.h
iio: common: scmi_sensors: use HZ macro from units.h
