Allow device ID arrays in the PCI driver structure

Browse Source 
Many PCI devices share the very same driver despite having different
PCI device IDs, which causes a lot of copy and paste of driver
definitions.

This change introduces a way to specify the array of acceptable
device IDs in a single driver entry. As an example the Intel
{Sandy|Ivy} Bridge SATA driver is being modified to use a single
driver structure for all different SATA controller flavors, a few
more Ivy Bridge IDs are being added as well.

BUG=none
TEST=manual
  . modified coreboot brought up an Ivy Bridge platform all the
    way to Linux login screen.
