MPTAPLE: generate from devicetree.cb

Browse Source 
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.
