The entry point function of this driver, InitializePciHostBridge(), and the static storage duration objects it relies on, are speculatively generic -- they nominally support more than one host bridges, but (a) the code hardwires the number of host bridges as 1, (b) it's very unlikely that we'd ever like to raise that number (especially by open-coding it). So let's just remove the the nominal support, and simplify the code. This patch is best viewed with "git show -b".
