MIPS: BCM47xx: Include bcm47xx_sprom.h

Now that bcm47xx_sprom.h contains a prototype for bcm47xx_fill_sprom,
include that header file directly from bcm47xx.h.

MIPS: BCM47xx: Fetch board info directly in callback function

This drops another symbol dependency between setup.c and sprom.c which
will allow us to make SPROM code a separated module (and share it with
ARM).
Patch tested on Linksys WRT300N V1.

MIPS: BCM47xx: Read board info for all bcma buses

Extra bcma buses may be totally different models, see following dump:
boardtype=0x0646
pci/1/1/boardtype=0x0545
pci/2/1/boardtype=0x62b
We need to detect them properly to allow drivers apply some board
specific hacks.

MIPS: BCM47xx: Move NVRAM header to the include/linux/.

There are two reasons for having this header in the common place:
1) Simplifying drivers that read NVRAM entries. We will be able to
safely call bcm47xx_nvram_* functions without #ifdef-s.
2) Getting NVRAM driver out of MIPS arch code. This is needed to support
BCM5301X arch which also requires this NVRAM driver. Patch for that
will follow once we get is reviewed.

MIPS: BCM47XX: only print SoC name in system type in cpuinfo

Recently the output of "system type" in /proc/cpuinfo was changed to
Broadcom BCM4730 (Some sample board), but it is better to just print
the SoC name in the "system type" entry. The board name will be added
in the machine entry later.

MIPS: BCM47xx: sprom: read values without prefix as fallback

There are bcma based devices like the Linksys E2000 out there, which do
have one ieee80211 core, but no PCIe core and they are using no
prefixes for the sprom. In addition some values like boardtype are
stored without a prefix for the main SoC chip also when they have an
additional PCIe wifi chip with an own boardtype var on some devices.

The Ethernet addresses are now also read out correctly without a prefix
so calling bcm47xx_fill_sprom_ethernet is not needed any more.

bcma: add boardinfo struct

This struct contains information about the board, the chip is running
on. The struct is filled for PCIe devices and SoCs. This information is
used by b43 and will be used by brcmsmac soon.

MIPS: BCM47XX: move and extend sprom parsing

Move the sprom parsing from nvram into sprom.c. There are all values
needed for sprom version 1 to 9 read from nvram and there are more
sanity checks added. This is based on the sprom parsing in the open
source part of the Broadcom SDK.

bcm47xx: add support for bcma bus

CPUs on the new SoC and on the old ons using ssb bus there are no Mips

bcm47xx: prepare to support different buses

Prepare bcm47xx to support different System buses. Before adding
support for bcma it should be possible to build bcm47xx without the
need of ssb. With this patch bcm47xx does not directly contain a
ssb_bus, but a union contain all the supported system buses. As a SoC
just uses one system bus a union is a good choice.
