Subject: [PATCH v2 0/2] iio: fix suspend and resume triggering for bmi160 and bmi270

Two imu devices bmi160 and bmi270 are similar to bmi323, with the same bug and
a common usecase: fix the aforementioned bug about triggering not resuming
after sleep in the same way it was solved for the bmi323 device driver.

The bmi270 patch has been tested on a device where the device irq pin
is connected to the CPU ensuring it doesn't cause harm to devices that
do not use hrtimer or other external triggers.

Changelog from v1 [1]
- include linux/pm.h where needed
- used "Closed" to reference the solved issue for each driver
- merged two lines into one (on both drivers)
