The PCI controller can have DT subnodes describing extra properties
of particular PCI devices, ie. a PHY attached to an EHCI controller
on a PCI bus. This patch parses those DT subnodes and assigns a node
to the PCI device instance, so that the driver can extract details
from that node and ie. configure the PHY using the PHY subsystem.

In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

Only PCI device 1 and 2 is populated on the R-Car Gen2 internal
PCIe controller. Ignore all other devices. This fix prevents a
duplication of OHCI controller response on slot 0 and 1.

Most FSL PCIe controllers expects 333 MHz PCI reference clock.
This clock is derived from the CCB but in many cases the ref.
clock is not 333 MHz and a divisor needs to be configured.

This adds PEX_CCB_DIV #define which can be defined for each
type of CPU/platform.

This introduces two new APIs dm_pci_find_capability() and
dm_pci_find_ext_capability() to get PCI capability address and
PCI express extended capability address for a given PCI device.

We have "struct sandbox_pci_priv" in pci_sandbox driver. To avoid
confusion, rename the emul's priv to "struct sandbox_pci_emul_priv".

At present all emulated sandbox pci devices must be present in the
device tree in order to be used. The real world pci uclass driver
supports pci device driver matching, and we should add such support
on sandbox too.

The correct driver data comes from the matching 'id' instead of
'find_id' in pci_find_and_bind_driver().
