[coreboot] [RFC] kill unwanted_vpci, use "hidden" property instead

[Carl-Daniel Hailfinger]

Hi,

since the Geode/CS553x platform emulates PCI headers for
chipset/processor devices, we have the ability to switch off that
emulation and hide those virtual PCI headers. Right now we do this in a
fairly uncoordinated fashion: I counted at least three different
open-coded code sequences with the same effect.

My current plan is:
- encapsulate all those code sequences into calls of one or two functions
- switch all calls from hide_vpci(some_value_calculated_by_hand) to
hide_vpci_dev(struct device *)
- replace the central array of hand-calculated values with a
per-PCI-device "hidden" property.

This should result in an overall improvement of code readability and a
reduction of code size. As a nice side benefit the dts is a lot easier
to manipulate.

Questions? Comments?

Regards,
Carl-Daniel
