Some chromebook EC provides a counter to get all vsync coming from the back
camera.
This series introduces a patch coming from chromebook kernel 4.4 designed as an
IIO counter. As IIO counter will be deprecated in favor of counter, I rebase the
original patch and support the new counter API.

The serie need to be merged after https://lkml.org/lkml/2019/7/9/305

Changes since v1:
- Drop code related to IIO_COUNT
- Add external attribute to the counter driver
- Add cros_ec_sensors_sync.c to MAINTAINERS file
