GPIO handling code has been removed from the drivers (since
this is now handled by the ACPI core) in commit 0f0796509c ("iio:
remove gpio interrupt probing from drivers that use a single interrupt").
Remove the include for linux/gpio/consumer.h since it is no longer
used.

Some i2c busses (e.g.: Synopsys DesignWare I2C adapter) need to
enable/disable the bus at each i2c transfer and must wait for
the enable/disable to happen before sending the data.
When reading data in the trigger handler, the bmc150 accel driver does
one bus transfer for each axis. This has an impact on the frequency
of the accelerometer at high sample rates due to additional delays
introduced by the bus at each transfer.
Reading all axis values in one bus transfer reduces the delays
introduced by the bus.

Use available_scan_masks to allow the iio core to select
the data to send to userspace depending on which axes are
enabled, instead of doing this in the driver's interrupt
handler.

At probe, runtime pm should be setup before registering the sysfs interface so
that all the power attributes are accurate and functional when registering.
Also, when removing the device we should unregister first to make sure
that the interfaces that may result in wakeups are no longer available.
Fix this behaviour for the following drivers: bmc150, bmg160, kmx61,
kxcj-1013, mma9551, mma9553, rpr0521.
