Karl Palsson b40c72828d stm32: i2c: provide "transfer" level helper routines
For both v1 and v2, provide routines to help do arbitrary length
write/read transfers.

Tested with multiple byte writes and reads, for both 100khz and 400khz,
with repeated starts and stop/starts.  However, only tested (presently)
with a single i2c target device, a Sensiron SHT21 sensor.  Extended
testing against eeproms and alternative devices would be useful
