Vincent Palatin 231319c08c stm32: implement SMBUS-style read block/string ...

Add support in the I2C driver for SMBUS-style read block operations.
As defined by the SMBUS standard, a "read block" returns at most 32
bytes of data plus the size of response as the first byte.

It's used to read smart battery strings such as manufacturer or model.
