mpc83xx: MPC837xEMDS: Use hwconfig instead of pci_external_arbiter variable
Since we have simple hwconfig interface now, we don't need
pci_external_arbiter variable any longer.

mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards

mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards
The MPC837xE-MDS board's CPLD can auto-detect if the board is on the PIB,
standalone or acting as a PCI agent. User's Guide says:
- When the CPLD recognizes its location on the PIB it automatically
configures RCW to the PCI Host.
- If the CPLD fails to recognize its location then it is automatically
configured as an Agent and the PCI is configured to an external arbiter.
This sounds good. Though in the standalone setup the CPLD sets PCI_HOST
flag (it's ok, we can't act as PCI agents since we receive CLKIN, not
PCICLK), but the CPLD doesn't set the ARBITER_ENABLE flag, and without
any arbiter bad things will happen (here the board hangs during any config
space reads).
In this situation we must disable the PCI. And in case of anybody really
want to use an external arbiter, we provide "pci_external_aribter"
environment variable.

mpc83xx: cleanup System Part and Revision ID Register (SPRIDR) code
in the spirit of commit 1ced121600b2060ab2ff9f0fddd9421fd70a0dc6,
85xx's "Update SVR numbers to expand support", simplify SPRIDR processing
and processor ID display. Add REVID_{MAJ,MIN}OR macros to make
REVID dependent code simpler. Also added PARTID_NO_E and IS_E_PROCESSOR
convenience macros.
