brcm63xx: rename target to bcm63xx

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.

+Subject: [PATCH 2/4] bcm63xx_enet: use platform data for dma channel numbers
+
+To reduce the reliance on device ids, pass the dma channel numbers to
+the enet devices as platform data.
