periph/i2c: convert char to uint8_t where applicapable
...
In general, data transferred through I2C are bytes and thus should have
type uint8_t, not char.
Also convert uint8_t ptrs to void ptrs

stm32f1/i2c: do not block in case of error
...
Due to the errata of some of the stm32f1xx family, the i2c lines need
to be toggled when setting up the peripheral. This however seems to
hang some i2c slaves which do not ack the first message sent after
initialization. This caused the code to be stucked waiting for the
never coming ACK. The same situation could occur when a byte was not
acked due to whatever reason.
The previous implementation of the i2c driver didn't allow recovery
on these situations. Now the driver does not block forever but rather
returns a <0 code to indicate that the transaction was not succesful.

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.

stm32f1/i2c: Disable I2C module before initialization
...
When initializing multiple drivers connected to the same
I2C bus, the bus should be disabled before pin toggeling
and reinitialization.

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.
