There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

Set up IGD OpRegion in northbridge and fill in GNVS' aslb.
At this point GNVS already has been set up by SSDT injection.
Required for future VBT patches that will:
* Use ACPI memory instead of CBMEM
* Use common implementation to locate VBT
* Fill in platform specific values

Die if cbmem_add can't allocate memory for the hob pointer. This
shouldn't ever happen, but it's a reasonable check.
- fsp_broadwell_de already had a check, but it returned to someplace
inside the FSP. Just die instead.

MMCONF was explicitly used here to avoid races of 0xcf8/0xcfc access
being non-atomic and/or need to access 4kiB of PCI config space.
All these platforms now have MMCONF_SUPPORT_DEFAULT.
I liked the style of code in pci_mmio_cfg.h more, and used those to
replace the ones in io.h.

The Intel cave creek chipset needs to have port 80 routing configured
before any post codes can be sent to port 80h. Sending post codes out
before the routing is done will hang the system.
This patch allows us to disable the first couple of post codes that go
out before the routing can be configured.
The Kconfig symbol is selected by the cave creek chipset (fsp_i89xx).
