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.

Linux 2.6.11 seems to require a certain order in CPUs listed in mptable,
so enforce it. This was only done on arima/hdama, but now is generic.
Unfortunately this is somewhat slow.

The last couple of lines of every mptable function were mostly
identical. Refactor into common code, a new function mptable_finalize.

We copied pretty much the same code for generating mptable entries for
local interrupts (with some notable exceptions).
This change moves these lines into a generic function "mptable_lintsrc"
and makes use of it in many places.
The remaining uses of smp_write_lintsrc should be reviewed and replaced
by mptable_lintsrc calls where possible, and smp_write_lintsrc made static.

We currently use "COREBOOT" unconditionally as the "OEM ID" in our
mptable.c files, and hardcode the mainboard name in mptable.c like this:
mptable_init(mc, "DK8-HTX ", LAPIC_ADDR);
However, the spec says
"OEM ID: A string that identifies the manufacturer of the system hardware."
(Table 4-2, page 42)
so "COREBOOT" doesn't match the spec, we should use the hardware vendor name.
Thus, use CONFIG_MAINBOARD_VENDOR which we have already as the "OEM ID"
(truncate/fill it to 8 characters as per spec).
Also, use CONFIG_MAINBOARD_PART_NUMBER (the board name) as "product ID",
and truncate/fill it to 12 characters as per spec, if needed.
Abuild-tested.
