i2c-stm32f0: Adjust scope of the I2C host code
HAS_TASK_HOSTCMD is not a good indicator that we intend to use I2C Host Commands
On platforms such a veyron we use an STM32F0 with SPI HC for example however
i2c-stm32f0.c was very eager to still provide host commands via I2C.
If one wants to use I2C host commands they need to define
CONFIG_HOSTCMD_I2C_SLAVE_ADDR anyway, so the presence of that is a better
indicator.
The boards that want I2C host commands are ryu and samus_pd.
veyron/pinky needs SPI host commands, so this patch makes this case possible.
The rest of the boards that use STM32F0 do not have HAS_TASK_HOSTCMD set.
BUG=None
TEST=make buildall -j
BRANCH=None
