brcm47xx: use "firmware" partition name

Some time ago, after switching to the mainline bcm47xxpart driver
following patch has been applied:

commit 03cef8725d2062335ffc3de50fc037b294fd458c

    brcm47xx: use old partition names again for kernel 3.8

    This fixes sysupgrade. The partition names are used all over the Internet in various howtos.

    Thank you russell for spotting this problem.

I propose to revert this change and make sysupgrade use "firmware"
instead. This makes brcm47xx compatible with widely used ar71xx and
after all "firmware" sounds like a much better name for... the firmware.

This change doesn't affect "sysupgrade" usage, because it never takes a
partition name as a parameter. This change only affects users using mtd
tool directly. Hopefully there are not many howtos using "mtd" command.

brcm47xx: add cpu overwrites 

bcm47xx misses cpu overwrites for the features of the CPUs used in 
these SoCs.
Instead of manually checking, it is now known at compile time for some 
options and the compiler is able to remove the checks and optimize the 
code.

brcm47xx: add vectored interrupts

This adds support for vectored interrupts in this SoC.
This is supported by the 74K cpus.
