Subject: [PATCH v3 0/4] iio: accel: adxl345: Split driver into core and I2C then add SPI support

This patchset modifies the adxl345 to use regmap. In doing so, we can
easily introduce SPI support and let regmap handle the rest.

Recap of basic features: read_raw for x, y and z axes, scale. After
applying this series, driver now supports the SPI protocol and enumeration
of device via device tree.

Changes from v2:
* Drop PATCH 4 iio: accel: adxl345: Add ACPI support
* Add OF match table on both I2C and SPI files and document them

Changes from v1:
iio: accel: adxl345: Use I2C regmap instead of direct I2C access
* Move other deletions from patch 2 in here -- make it clear what got deleted
  and/or modified that is hard to see previously
* Introduce the driver header file "adxl345.h" here instead of doing it in the
  next patch
* Completely omit traces of i2c_client and let this file (adxl345.c) mirror the
  core file on the next patch.
* Improve debugging print about invalid device ID in probe.
iio: accel: adxl345: Split driver into core and I2C
* Update Kconfig to Jonathan's preferred style
* Improve similarity index from 78% to 100% (rename detection)
iio: accel: adxl345: Add ACPI support
* Correct acpi_device_id: ADX0345 -> ADS0345
