reset: tps380x: Add TPS380x device driver supprt

Browse Source 
The TI TPS380x family [1] is a voltage supervisor with a dedicated
manual reset (mr) line input and a reset output. The chip(s) have a
build in reset delay, depending on the chip partnumber. This simple
driver addresses this so the cosumer don't need to care about it.
