Before it was tried to initialize the deactivated PCIe core in client
mode, but this causes the SoC to hang. Just do not initialize it at all
and ignore the core it is not working and nothing is connected to it
when the specific bit is set in the boardflags.

The BCM4706 has two PCIe host controller on the bcma bus. For PCIe
client mode it is assumed that there is only one PCIe controller so the
PCIe driver, like b43 and brcmsmac are accessing the first PCIe
controller when they want to issue a operation on the host controller.

Having bus number printed makes it much easier to anaylze logs on
systems with more buses. For example Netgear WNDR4500 has 3 AMBA buses
in total, which makes standard log really messy.

The chip IDs are used all over bcma and no constants where defined.
This patch adds the constants and makes bcma use them.

PCI Memory Resource start address and size are variable, dependent on
the H/W configuration. Modify the computation of io_map_base to use the
computed values.

The following is seen during allmodconfig builds for MIPS:
drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration
of function 'pcibios_enable_device' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1
Most likey introduced by commit 49dc957715
"bcma: add PCIe host controller"
Add the header instead of implicitly assuming it will be present.
Sounds like a good idea, but that alone doesn't fix anything.
The real problem is that the Kconfig has settings related to whether
PCI is possible, i.e.
config BCMA_HOST_PCI_POSSIBLE
bool
depends on BCMA && PCI = y
default y
config BCMA_HOST_PCI
bool "Support for BCMA on PCI-host bus"
depends on BCMA_HOST_PCI_POSSIBLE
...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't
have any dependencies on the above. Add one.

Some SoCs have a PCIe host controller to make it possible to attach
some other devices to it, like an other Wifi card.
This code was tested with an Netgear WNDR3400 (bcm4716 based), but
should work with all bcma based SoCs.

bcma_core_pci_hostmode_init() has to be in __devinit as it will call a
function in that section and so all functions calling it also have to
be in __devinit.

We must not init it like clientmode one, it would break device (tested
by Hauke on BCM4718). Add stub hostmode driver for now.
