powerpc/eeh: Rename flag EEH_PE_RESET to EEH_PE_CFG_BLOCKED
The flag EEH_PE_RESET indicates blocking config space of the PE during reset time. We potentially need block PE's config space other than reset time. So it's reasonable to replace it with EEH_PE_CFG_BLOCKED to indicate its usage. There are no substantial code or logic changes in this patch.
