So far interrupt routing works pretty well for any on-chip devices

Linux kernel is smart enough to do interrupt swizzling and figure
out device's irq using its parent bridge's interrupt routing info

x86: Add MultiProcessor (MP) table APIs
The MP table provides a way for the operating system to support
for symmetric multiprocessing as well as symmetric I/O interrupt
handling with the local APIC and I/O APIC. We provide a bunch of
APIs for U-Boot to write the floating table, configuration table
header as well as base and extended table entries.

x86: Remove inline for lapic access routines
Remove inline for lapic access routines and expose lapic_read()
& lapic_write() as APIs to read/write lapic registers. Also move
stop_this_cpu() to mp_init.c as it has nothing to do with lapic.

I/O APIC registers are addressed indirectly. Add io_apic_read() and
io_apic_write() routines to help register access. Two macros for I/O
APIC ID and version register offset are also added.

x86: Reduce PIRQ routing table size
There is no need to populate multiple irq info entries with the same
bus number and device number, but with different interrupt pin. We
can use the same entry to store all the 4 interrupt pin (INT A/B/C/D)
routing information to reduce the whole PIRQ routing table size.

x86: Ignore function number when writing PIRQ routing table
In fill_irq_info() pci device's function number is written into
the table, however this is not really necessary. The function
number can be anything as OS doesn't care about this field,
neither does the PIRQ routing specification. Change to always
writing 0 as the function number.

x86: queensbay: Correct Topcliff device irqs
There are 4 usb ports on the Intel Crown Bay board, 2 of which are
connected to Topcliff usb host 0 and the other 2 connected to usb
host 1. USB devices inserted in the ports connected to usb host 1
cannot get detected due to wrong IRQ assigned to the controller.
Actually we need apply the PCI interrupt pin swizzling logic to all
devices on the Topcliff chipset when configuring the PIRQ routing.
This was observed on usb ports, but device 6 and 10 irqs are also
wrong. Correct them all together.
