programmer.h: Make pacc global state static local

chipset_enable.c has some fragile pci logic to deal
with Intel's complexity of finding the SPI controller
on the ICH.

Here we provide function to allow pushing the scope of
pci access global state inwards into a static local of
just pcidev. While by no means perfection, this does
at least make it easier to reason about 'pacc' control
flow now.

BUG=none
TEST=builds
