Hello,

The first patch adds support for checking the sensor ID by reading
MODEL_IDENTIFICATION register and seeing if it returns the value 0xEE

The second patch adds support for continuous mode in the sensor by using
buffers. We enable the sensor's continuous mode in the buffer_postenable
function.
Replaced the irq handler with a threaded irq handler in order to perform
I2C reads for the data. The continuous mode can be disabled by disabling
the buffer.
Added a trigger to the device for the continuous mode. Also validating that
the device uses the internal trigger provided by us.

Changes in v3:
- Added "asm/unaligned.h" include to fix `-Wimplicit-function-declaration`.
- The above error was pointed during testing by kernel-test-robot
- Link to v2: https://lore.kernel.org/linux-iio/[e-mail]/T/#t

Changes in v2:
- Added a trigger for the device
- Added a poll function for the triggered buffer setup
- Performed the data reading and pushing to buffers in the poll function
- Minor code refactoring

- Link to v1: https://lore.kernel.org/linux-iio/[e-mail]/T/#t
