PCIe RPC (Root Port Configuration) straps will force-disable some root
port functions if some root ports have a width greater than x1. In two
cases, this affects the last function. The PCIe init code will never
finish configuring the root ports if that is the case: it assumes that
the last function will eventually run through the code, but it doesn't.
If PCIe initialization does not complete, pressing the power button will
not power off the board, unless it is held for about five seconds. Also,
Windows 10 will show a BSOD about MACHINE CHECK EXCEPTION, and lock up
instead of rebooting. Depending on the microcode version, the BSOD may
not be visible. This happens even when the root port is not populated.
Use the strap fuse configuration value to know which configuration the
PCH is strapped to. If needed, update the number of ports accordingly.
In addition, print the updated value to ease debugging PCIe init code.
Existing code in coreboot disagrees with public documentation about the
root port width straps. Assume existing code is correct and document
these assumptions in a table, as an explanation for the added code.
Tested on Asrock B85M Pro4, PCIe initialization completes successfully.

People who know a lot more about electrons and stuff than I do tell me
that leaving a HiZ pin floating without a pull resistor may waste power.
So if we find a pin to be HiZ when reading tristate strapping GPIOs, we
should make sure the internal pull-down is enabled when we're done with
it. (For pins that are externally pulled high or low, we should continue
to leave the internal pull disabled instead.)

This change configures GPIO_89 as PAD_NC in baseboard GPIO

speakers to work, GPIO_89 is configured as PAD_GPO driven high on
pre-v3.6 schematics.
