serial: drop SERIAL_8250_DEPRECATED_OPTIONS



In 3.7, 8250 was unintentionally renamed to 8250_core. This happened in
the commit 835d844d (8250_pnp: do pnp probe before legacy probe).
This made 8250.<xxxx> module options effectively defunct. Instead,
8250_core.<xxxx> worked.

In 3.9, the commit f2b8dfd9 (serial: 8250: Keep 8250.<xxxx> module
options functional after driver rename) made the original options work
again by introducing a hack.

Later in 3.9, the commit 9196d8ac (TTY: 8250, revert module name
change) changed the module name back to 8250 (from 8250_core). Since
then, the hack was there to support the transient 8250_core.<xxxx>
options. Those were present only in the 3.7..3.9 range.

These transient options were deprecated by 9326b047 (TTY: 8250,
deprecated 8250_core.* options) in v3.9 too.

Now, after those 12 years, it is time to get rid of this hack
completely.
