For the repeated start, we have to keep the AUTOEND flag reset for both the transactions before and after the reStart. Not doing so would lead to a premature STOP condition and the failure of the reStart

- Created a different file for the f7 driver implementation
- Added the support for FAST_PLUS speed mode for 1Mbps communication
- For now timing register values hardcoded for each speed mode (considering I2CCLK = 48MHz); to be changed
- Now test for f7 test also the FAST_PLUS speed mode

But we have bought a 32.768MHz crystal instead of a 32.768KHz one, so we'll test it again when we change it
