Arend van Spriel c4bff5d99d brcmfmac: fix bus interface selection in Kconfig
The kernel configuration for the driver could result in
compilation issues as reported by Randy Dunlap. His results
are show below:

"on x86_64:

when
CONFIG_MMC=m
CONFIG_BRCMUTIL=y
CONFIG_BRCMFMAC=y
CONFIG_BRCMFMAC_SDIO=y

This bool kconfig symbol:

config BRCMFMAC_SDIO
	bool "SDIO bus interface support for FullMAC driver"
	depends on MMC

allows BRCMFMAC_SDIO to be y even when MMC=m.

Is there a reasonable solution to this?

This causes many build errors:

drivers/built-in.o: In function `brcmf_sdio_assert_info':
dhd_sdio.c:(.text+0x39609b): undefined reference to `sdio_claim_host'
dhd_sdio.c:(.text+0x3960d9): undefined reference to `sdio_release_host'
drivers/built-in.o: In function `brcmf_sdio_readframes':
dhd_sdio.c:(.text+0x396a62): undefined reference to `sdio_claim_host'
dhd_sdio.c:(.text+0x396a9b): undefined reference to `sdio_release_host'
..."

This patch adds the appropriate logic in Kconfig to resolve
these issues. The solution was provided by Hauke Mehrtens.

---help---
This module adds support for PCIe wireless adapters based on Broadcom
IEEE802.11n SoftMAC chipsets. It also has WLAN led support, which will
be available if you select BCMA_DRIVER_GPIO. If you choose to build a
module, the driver will be called brcmsmac.ko.

select BRCMUTIL
---help---
This module adds support for embedded wireless adapters based on
Broadcom IEEE802.11n FullMAC chipsets. It has to work with at least
one of the bus interface support. If you choose to build a module,
it'll be called brcmfmac.ko.

bool "SDIO bus interface support for FullMAC driver"
depends on (MMC = y || MMC = BRCMFMAC)

select FW_LOADER
default y
---help---
This option enables the SDIO bus interface support for Broadcom
IEEE802.11n embedded FullMAC WLAN driver. Say Y if you want to
use the driver for a SDIO wireless card.
config BRCMFMAC_USB
bool "USB bus interface support for FullMAC driver"

This option enables the USB bus interface support for Broadcom
IEEE802.11n embedded FullMAC WLAN driver. Say Y if you want to
use the driver for an USB wireless card.
config BRCM_TRACING
bool "Broadcom device tracing"
depends on BRCMSMAC || BRCMFMAC
---help---
If you say Y here, the Broadcom wireless drivers will register
with ftrace to dump event information into the trace ringbuffer.
Tracing can be enabled at runtime to aid in debugging wireless
issues. This option adds a small amount of overhead when tracing
is disabled. If unsure, say Y to allow developers to better help
you when wireless problems occur.
config BRCMDBG
bool "Broadcom driver debug functions"
depends on BRCMSMAC || BRCMFMAC
---help---
Selecting this enables additional code for debug purposes.
