Add support for the Bosch BMI260 IMU to the BMI270 device driver.
The BMI270 and BMI260 have nearly identical register maps, but have
different chip IDs and firmware.
The BMI260 is the IMU on a number of handheld PCs. Unfortunately,
these devices often misidentify it in ACPI as a BMI160 ("BMI0160," for
example), and it can only be correctly identified using the chip
ID. I've changed the driver to fail if the chip ID isn't recognized so
the firmware initialization data isn't sent to incompatible devices.
Also add triggered buffer and scale / sampling frequency attributes,
which the input tools commonly used on handheld PCs require to support
IMUs.
Like the BMI270, the BMI260 requires firmware to be provided.
