Sandybridge: Display platform information early

It is important to have the system configuration reported as early as
possible to have a better idea what exact chipset the platform is
running with.

This change adds code to have an early coreboot module report the CPU
and PCH information. CPU info includes the 32 bit feature information
word, the symbolic processor brand string, and information about some
features support, as obtained through CPUID instructions.

The PCH information includes the symbolic device name and PCI device
version.
