drivers/pcf857x: Move compile time check to compilation unit

Browse Source 
This allows including the header without using the module. Obviously,
calls to the functions provided by the header won't like without using
the module. But including the header can still be useful for e.g.:

    if (IS_USED(MODULE_PCF857x)) {
        /* make use of the module */
    }

In the above example all calls to pcf857x functions would be optimized
out when the module is not used, full compile checks happen in either
case.
