MIPS: BCM47xx: Make serial explicitly non-modular

The Makefile entry controlling compilation of this code is "obj-y"
meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

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.

bcm47xx: add support for bcma bus

This patch add support for the bcma bus. Broadcom uses only Mips 74K
CPUs on the new SoC and on the old ons using ssb bus there are no Mips
74K CPUs.

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.

[MIPS] Add support for BCM47XX CPUs.

Note that the BCM4710 does not support the wait instruction, this
is not a mistake in the code.

It originally comes from the OpenWrt patches.
