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: [RFC] jffs2: work around unaligned accesses failing on bcm63xx/smp
Unligned memcpy_fromio randomly fails with an unaligned dst. Work around
it by ensuring we are always doing aligned copies.
Should fix filename corruption in jffs2 with SMP.
