STM32F767ZI - I2C FastModePlus not properly enabled

Following HAL update, MACRO __HAL_SYSCFG_FASTMODEPLUS_ENABLE has been replaced by I2C API function HAL_I2CEx_EnableFastModePlus.

In targets/TARGET_STM/i2c_api.c

#if defined(I2C1_BASE) && defined(__HAL_SYSCFG_FASTMODEPLUS_ENABLE) && defined (I2C_FASTMODEPLUS_I2C1)
if (obj_s->i2c == I2C_1) {
HAL_I2CEx_EnableFastModePlus(I2C_FASTMODEPLUS_I2C1);
}

However, macro __HAL_SYSCFG_FASTMODEPLUS_ENABLE being now undefined, i guess we have to remove it in order to properly enable I2C FastModePlus.

Proposal:

#if defined(I2C1_BASE) && defined (I2C_FASTMODEPLUS_I2C1)
if (obj_s->i2c == I2C_1) {
HAL_I2CEx_EnableFastModePlus(I2C_FASTMODEPLUS_I2C1);
}

Thanks @durets

@ABOSTM @jeromecoutant
at first glance, the proposed fix makes senses (to be applied to all the I2C instances).
can you have a look and create a corresponding Pull Request ?
