Currently, 83xx, 86xx, and 85xx have a lot of duplicated code
dedicated to defining and manipulating the LBC registers. Merge
this into a single spot.
To do this, we have to decide on a common name for the data structure
that holds the lbc registers - it will now be known as fsl_lbc_t, and we
adopt a common name for the immap layouts that include the lbc - this was
previously known as either im_lbc or lbus; use the former.
In addition, create accessors for the BR/OR regs that use in/out_be32
and use those instead of the mismash of access methods currently in play.
I have done a successful ppc build all and tested a board or two from
each processor family.

move the BRx_* and ORx_* left behind in mpc85xx.h
The same is needed for mpc8xx.h and mpc8260.h (defines are almost
the same, just few differences which needs some attention though).
But the bad news for mpc8xx and mpc8260 is that there are a lot of users
of these defines. So this cleanup I'll leave for the "better times".

This patch moves Freescale Localbus defines out of mpc83xx.h, so we could
use it on MPC85xx and MPC86xx processors.

From: Ed Swarthout <[email protected]>
Support external interrupts from platform to eliminate system hangs.
Define CONFIG_INTERRUPTS board configure option to enable.
Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC.
Remove extra cpu initialization redundant with hardware initialization.
Whitespace cleanup.
Define and use _START_OFFSET consistent with other processors using
ppc_asm.tmpl
Move additional code from .text to boot page to make room for
exception vectors at start of image.
Handle Machine Check, External and Critical exceptions.
Fix e500 machine check error determination in traps.c
TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.
