Refactors the remaining I2C drivers to use the shared driver class initialization priority configuration, CONFIG_I2C_INIT_PRIORITY, to allow configuring I2C drivers separately from other devices. This is similar to other driver classes. The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the existing default initialization priority for most drivers.
