powerpc/eeh: Block PCI config access during reset
Function pcibios_set_pcie_reset_state() can be used to do PCI reset. PCI config access during the reset usually causes EEH errors unexpectedly. In order to avoid the EEH error, the patch blocks PCI config access during reset with the help of flag EEH_PE_RESET, which is similar to what we did in EEH PE reset path.
