CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This code is based on code from pcie_misc_config_fixup() in brcmsmac.
This patch is part of the move of pci specific code from brcmsmac to
bcma.

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.

There are many magic numbers used in the PCIe code. Replace them with
some constants from the Broadcom SDK and also use them in the pcie host
controller.

Function managing IRQs is needed for external drivers like b43.
On the other side we do not expect writing any hosts drivers outside of
bcma, so this is safe to do not export functions related to this.

Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.
In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.
Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).
Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.
