[PATCH v3 0/8] Add support for best effort block read emulation

This is version 3 for adding i2c_smbus_read_i2c_block_data_or_emulated to i2c-core. The i2c core part is the same as in v2, but I have added 3 more users for iio drivers. Changes in v2: - changed bmc150-accel, kxcjk-1013 and bmg160 drivers to use i2c_smbus_read_i2c_block_data_or_emulated Changes
