Subject: [PATCH] PCI: iproc: Add PCI_DOMAIN dependency to PCI Kconfig

From: Jon Mason <jonmason@...adcom.com>

2+ PCI devices fail to be discovered due to each bus having the same
PCI domain.  This is because the domain defined in the device tree file
is not being added due to PCI_DOMAIN not being enabled.  So, every PCI
bus has a domain of zero.  When PCI_DOMAIN is selected by the Kconfig,
it picks-up the domain defined in the device tree file and everything
works as expected.

Since both PCIE_IPROC_PLATFORM and PCIE_IPROC_BCMA need PCI_DOMAIN,
moving it to PCIE_IPROC (so it can be automatically selected for both).
