omap_gpmc: Fix handling of FIFOTHRESHOLDSTATUS bit

The OMAP3 TRM is inconsistent about whether the GPMC FIFOTHRESHOLDSTATUS

FIFOTHRESHOLD. Apparently the underlying functional spec from which

memory: Fix old_portio vs non-zero offset

The legacy functions that we're wrapping expect that offset
to be included in the register.  Indeed, they generally
expect the absolute address and then mask off the "high" bits.

The FDC is the first converted device with a non-zero offset.

memory: temporarily suppress the subregion collision warning

After 312b4234, the APIC and PCI devices are colliding with each other.  This
is harmless in practice because the APIC accesses are special cased and never
make there way onto the bus.

Avi is working on a proper fix, but until that's ready, avoid printing the
warning.

440fx: fix PAM, PCI holes

The current implementation of PAM and the PCI holes is broken in several
ways:

  - PCI BARs are not restricted to the PCI hole (a BAR may hide memory)
  - PCI devices do not respect PAM (if a PCI device maps a region while
    PAM maps the region to RAM, the request will be honored)

This patch fixes things by introducing a pci address space, and using
memory region aliases to represent PAM regions, SMRAM, and PCI holes.

The memory hierarchy looks something like

system_memory
 |
 +--- low memory alias (0-0xe0000000)
 |      |
 |      +-- ram@0
 |
 +--- high memory alias (0x100000000-EOM)
 |      |
 |      +-- ram@0xe0000000
 |
 +--- pci hole alias (end of low memory-0x100000000)
 |      |
 |      +-- pci@end-of-low-memory
 |
 |
 +--- pam[n] (0xc0000-0xc3fff etc) (when set to pci, priority 1)
 |      |
 |      +-- pci@0xc4000 etc
 |
 +--- smram (0xa0000-0xbffff) (when set to pci/vga, priority 1)
        |
        +-- pci@0xa0000 etc

ram (simple ram region)

pci
 |
 +--- BARn
 |
 +--- VGA 0xa0000-0xbffff

 +--- ROMs
