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.
