iio: accel: BMC150: add support for other Bosch chips
The following chips are either similar or have only the resolution
different. Hence, change this driver to support these chips too:
BMI055 - combo chip (accelerometer part is identical to BMC150's)
BMA255 - identical to BMC150's accelerometer
BMA222E - 8 bit resolution
BMA250E - 10 bit resolution
BMA280 - 14 bit resolution
Additionally:
* add bmc150_accel_match_acpi_device() function to check that the device
has been enumerated through ACPI;
* rename bmc150_accel_acpi_gpio_probe() to bmc150_accel_gpio_probe()
since the ACPI matching has been moved to the new function. Also, this
will allow for the GPIO matching to be done against a device tree too, not only
ACPI tree;
* rename bmc150_scale_info struct member 'range' to 'reg_range' to be
consistent with the naming convention used elsewhere in the driver
and declare it u8, instead of int;
* change CONFIG description to list all supported chips;

- Say yes here to build support for the Bosch BMC150 accelerometer.
+ Say yes here to build support for the following Bosch accelerometers:
+ BMC150, BMI055, BMA250E, BMA222E, BMA255, BMA280.
+
Currently this only supports the device via an i2c interface.
This is a combo module with both accelerometer and magnetometer.
