Hans de Goede f68f3e3f5c iio: accel: mxc4005: Reset chip on probe() and resume()
[ Upstream commit 6b8cffdc4a31e4a72f75ecd1bc13fbf0dafee390 ]

On some designs the chip is not properly reset when powered up at boot or
after a suspend/resume cycle.

Use the sw-reset feature to ensure that the chip is in a clean state
after probe() / resume() and in the case of resume() restore the settings
(scale, trigger-enabled).
