regmap: new API regmap_multi_reg_write() definition
New API regmap_multi_reg_write() is defined that allows a set of reg,val pairs to be written to a I2C client device as one block transfer from the point of view of a single I2C master system. A simple demonstration implementation is included that just splits the block write request into a sequence of single register writes. The implementation will be modified later to support those I2C clients that implement the alternative non-standard MULTIWRITE block write mode so to achieve a single I2C transfer that will be atomic even in multiple I2C master systems.
