hwmon: (max34451) Work around lost page
When requesting new pages from the max34451 we sometimes see that the
firmware responds with stale or bad data to reads that happen
immediately after a page change. This is due to a lack of clock
stretching after page changing on the device side when it needs more
time to complete the operation.
To remedy this, the manufacturer recommends we wait 50us until
the firmware should be ready with the new page.
