phb4: Enforce root complex config space size of 2048
The root complex config space size on PHB4 is 2048. This patch sets
that size and enforces it when trying to read/write the config space
in the root complex.
Without this someone reading the config space via /sysfs in linux will
cause an EEH on the PHB.
If too high, reads returns 1s and writes are silently dropped.
