Subject: [PATCH v4 0/7] iio: accel: adxl345: Add spi-3wire feature

Pass a function setup() as pointer from SPI/I2C specific modules
to the core module. Implement setup() to pass the spi-3wire bus
option, if declared in the device-tree.

In the core module, then update data_format register
configuration bits instead of overwriting it. The changes allow
to remove a data_range field.
