PCI: add more checking to ICH region quirks
PCI: add more checking to ICH region quirks

Per ICH4 and ICH6 specs, ACPI and GPIO regions are valid iff ACPI_EN
and GPIO_EN bits are set to 1. Add checks for these bits into the
quirks prior to the region creation.

While at it, name the constants by macros.
