Help text

In 3.7 we renamed 8250 to 8250_core by mistake, so now we have to accept kernel parameters in both forms like 8250_core.nr_uarts=4 and 8250.nr_uarts=4. We now renamed the module back to 8250, but if anybody noticed in 3.7 and changed their userspace we still have to keep the 8250_core.* options around until they revert the changes they already did.

If 8250 is built as a module, this adds 8250_core alias instead.

If you did not notice yet and/or you have userspace from pre-3.7, it is safe (and recommended) to say N here.
