TTY: 8250, deprecated 8250_core.* options

They were introduced by mistake in 3.7. Let's deprecate them now. For
the reasons, see the text in Kconfig below.

Most people will say Y or M here, so that they can use serial mice,

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 8350_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.
