cpu/stm32f1: fixed i2c driver
...
the _stop() function now blocks until the transfer
is complete. Not waiting can lead to concurrent bus
access and subsequent to bus errors.

I2C bus, the bus should be disabled before pin toggeling
and reinitialization.

cpu/stm32f1: fix i2c master read for N>2 bytes
...
This fixes reading more than 2 bytes from the slave device.
In the current implementation the last byte was not read from
data register and the termination sequence buggy.
