Adrian Schmutzler e7bfda2c24 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 09/10] MIPS: BCM63XX: allow board files to provide sprom
fixups
Allow board_info files to supply fixups for the base sproms to adapt
them to the actual used sprom contents in case they do not use the
default ones.
