6bf2e54614 bcma: fix bcm4716/bcm4748 i2s irqflag
The default irqflag assignment for the I2S core on some Broadcom
4716/4748 devices is invalid and needs to be corrected (from the
Broadcom SDK).

e2aa19fadd bcma: return the mips irq number in bcma_core_irq
The irq signal numbers that are send by the cpu are increased by 2 from
the number programmed into the mips core by bcma.
Return the irq number on which the irqs are send in bcma_core_irq() now.

e3f05a42fa bcma: mips: explicit assign IRQ numbers
The assignment of the IRQs to the cores of the chips by iterating over
the cores is complicated and causes problems with SoC like the BCM4706
with two GMAC core where just one should get a dedicated IRQ number.
Now the code assigns the same IRQs to the cores as the code from the
Broadcom SDK does. If the SoC is not know the current assigned IRQs are
only read out and an error message is printed.

cbbc0138ef bcma: mips: fix clearing device IRQ
We were using wrong IRQ number so clearing wasn't working at all.
Depending on a platform this could result in a one device having two
interrupts assigned. On BCM4706 this resulted in all IRQs being broken.

49655bb8a5 bcma: just do the necessary things in early register on SoCs
Some parts of the initialization for chip common and the pcie core are
accessing the sprom struct, but it is not initialized at that stage.
Just do the necessary thing in the early register on SoCs and not the
complete initialization to read out the nvram from the flash chip.
After it is possible to read out the nvram, the sprom should be parsed
from it and the full initialization of the cores should be run.

d8f1bd2ffc bcma: fix regression in interrupt assignment on mips
The wrong interrupts where assigned to the cores in
bcma_core_mips_init(). This caused at least my serial console not to
response to any input.

This was caused by this patch which changed the order of the cores in
the list:

    bcma: add new cores at the end of list

This should be fixed properly later so that the correct interrupt
numbers are assigned to the cores independently from the ordering of
the list. This patch restores the old behavior again. I will look into
the problem more deeply later.

I also changed the order of the list with the cores and their assigned
interrupt number which gets printed to the log. Now they are printed in
the same order like all the other lists of cores and like it was done
before the patch which changed the order.

3d9d8af330 bcma: use custom printing functions
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.
