CTL_I2C_BUS_t *platform_private_i2c_bus_instance[];
platform_private_i2c_bus_instance contains the recoded instances of platform I2C buses, indexed using the platform I2C bus index. When an I2C bus is correctly configured by platform_configure_i2c_bus, the I2C bus instance is written to platform_private_i2c_bus_instance so that platform_i2c_bus can access and return an appropriate I2C bus.
