MPTAPLE: generate from devicetree.cb

This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.

Syntax in devicetree.cb:

ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>

The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

<http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
for details. YYERROR is fine as it does not invoke this
function.
- If this state is a consistent state with a default action, then
the only way this function was invoked is if the default action
is an error action. In that case, don't check for expected
tokens because there are none.
- The only way there can be no lookahead present (in yychar) is if
this state is a consistent state with a default action. Thus,
detecting the absence of a lookahead is sufficient to determine
that there is no unexpected or expected token to report. In that
case, just report a simple "syntax error".
- Don't assume there isn't a lookahead just because this state is a
consistent state with a default action. There might have been a
previous inconsistent state, consistent state with a non-default
action, or user semantic action that manipulated yychar.
- Of course, the expected token list depends on states to have
correct lookahead information, and it depends on the parser not
to perform extra reductions after fetching a lookahead from the
scanner and before detecting a syntax error. Thus, state merging
(from LALR or IELR) and default reductions corrupt the expected
token list. However, the list is correct for canonical LR with
one exception: it will still contain any token that will not be
accepted due to an error action in a later state.
