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.

Do not enable normal errors created during probe (master abort, perr,
and pcie Invalid Configuration access).

Add CONFIG_PCI_NOSCAN board option to prevent bus scan.

Remove rev 1 fixes.
Always set PICGCR_MODE.
Enable machine check and provide board config option
to set and handle SoC error interrupts.

Include MSSSR0 in error message.

Isolate a RAMBOOT bit of code with #ifdef CFG_RAMBOOT.

This patch fixes the negative consequences for 8xx of the recent
"ppc4xx: Clean up 440 exceptions handling" commit.

Signed-off-by: Rafal Jaworowski <raj@semihalf.com>

- Introduced dedicated switches for building 440 and 405 images required
  for 440-specific machine instructions like 'rfmci' etc.

- Exception vectors moved to the proper location (_start moved away from
  the critical exception handler space, which it occupied)

- CriticalInput now serviced (with default handler)

- MachineCheck properly serviced (added a dedicated handler and return
  subroutine)

- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
  unhandled and those not relevant for 4xx were eliminated)

- Eliminated Linux leftovers, removed dead code

MPC5200B systems are incorrectly reported as MPC5200 in U-Boot start-up
message. Use PVR to distinguish between the two variants, and print proper CPU
information.
