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. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

+Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If SoC has a CardBus we can set resources of device at slot 1 only. It's
+impossigle to set bridge resources as it simply overwrites device 1
+configuration and usually results in Data bus error-s.
