integrator: rewrite the AP PCI driver
The PCI support for the Integrator AP has apparently never
been finished and I strongly suspect that it has never worked,
so let's fix it. This is a list of the more or less
un-splittable changes done in this driver rewrite:
- Replace the register definitions stashed into the config
file (!) with a copy if the register file from the Linux
kernels arch/arm/include/asm/hardware/pci_v3.h
- Delete the unreadable gigantic macros that perform the
config accesses and replace them with copyedited code from
Linux arch/arm/mach-integrator/pci_v3.c
- Rewrite the rest of the setup code to use the
v3_[read|write][lwb]() accessors.
- Enable PCI by default in the AP board configuration.
- Fix checkpatch warnings and make code more conformant.

integrator: enable Vpp and disable flash protection
This enables Vpp and disables the flash protection on the
Integrator when starting U-Boot. The integrator/AP has double
protection mechanisms: this one and the EBI protection bit
(patch earlier), the Integrator/CP has only one line of
protection in these registers.

integrator: make flash writeable on boot
This reconfigures the EBI (External Bus Interface) on the
integrator so that chip select 1, handling the flash memory, is
set to writeable. Without this it is not possible for U-Boot to
access flash memory and it crashes on startup since CFI won't
work properly.
Since this is the first time we use the EBI, we create a header
file for its registers.

integrator: use io-accessors for board init
Casting around to *(volatile ulong *) doesn't look good, so include
the <asm/io.h> macros and use good old readl() instead.
