kernel: update bcma and ssb to wireless-testing master-2014-12-05

Browse Source 
This brings ssb and bcma to wireless-testing tag master-2014-12-05

In addition it also adds the ARM-BCM5301X-Add-IRQs-to-Broadcom-s-bus-
axi-in-DTS-f.patch which adds the irq number in a way it is done in the
mainline kernel.

Subject: [PATCH] ARM: BCM5301X: Add IRQs to Broadcom's bus-axi in DTS file
IRQ support for Broadcom's bus-axi driver bcma was merged into John
Linville's wireless tree and will show up in 3.19. This patch makes use
of this feature in the DTS file for the the BCM5301X SoCs. I left the
PCIe controller out, because this still needs some discussion.

Subject: [PATCH v3 2/2] bcma: get IRQ numbers from dt
It is not possible to auto detect the irq numbers used by the cores on
an arm SoC. If bcma was registered with device tree it will search for
some device tree nodes with the irq number and add it to the core
configuration.

Subject: [PATCH] ARM: BCM5301X: Add IRQs to Broadcom's bus-axi in DTS file
IRQ support for Broadcom's bus-axi driver bcma was merged into John
Linville's wireless tree and will show up in 3.19. This patch makes use
of this feature in the DTS file for the the BCM5301X SoCs. I left the
PCIe controller out, because this still needs some discussion.

Subject: [PATCH 1/3] bcma: make it possible to specify a IRQ num in
bcma_core_irq()
This moves bcma_core_irq() to main.c and add a extra parameter with a
number so that we can return different irq number for devices with more
than one.

Subject: [PATCH 3/3] bcma: get IRQ numbers from dt
It is not possible to auto detect the irq numbers used by the cores on
an arm SoC. If bcma was registered with device tree it will search for
some device tree nodes with the irq number and add it to the core
configuration.
