pciehp: evaluate _OSC/OSHP before controller init

Browse Source 
Current pciehp evaluates _OSC/OSHP method after some controller
initialization is done. So if evaluating _OSC/OSHP is failed, we need
to cleanup already initialized data structures or hardware. This
clearly is not robust way. With this patch, _OSC/OSHP evaluation is
done first.
