This adds support for Freescale's (now NXP's) FXLS8471Q accelerometer.
We use MMA8451Q's configuration because for what the driver supports,
FXLS8471Q is the same.
Support for FXLS8471Q's features (fast SPI interface and a larger FIFO,
among others) can be added to this driver anytime.

Add support for Freescale MMA9553L Intelligent Pedometer Platform.

- step counter (counts the number of steps using a HW register)
- step detector (generates an iio event at every step the user takes)
- activity recognition (rest, walking, jogging, running)
- speed
- calories
- distance
To get accurate pedometer results, the user's height, weight and gender
need to be configured.

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;
