Adrian Schmutzler 8fe5ad5d33 brcm47xx: rename target to bcm47xx
This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

When the Ethernet controller is powered down and someone wants to
access the mdio bus like the witch driver (b53) the system crashed if
PCI_D3hot was set before. This patch deactivates this power sawing mode
when a switch driver is in use.
