85b1f4d8ca treewide: remove execute bit and shebang from board.d files
So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in
target/linux/bcm47xx/base-files/etc/board.d/01_network

4dd5845f49 bmips: fix SMP CPU mapping
SMP isn't supported on BCM6358 since it has a shared TLB. Some boards boot
with CPU #1 instead of CPU #0, and this is currently not supported do to a
smp-bmips bug.

020e51facf bmips: split base-files into subtargets
Like done for several targets already, splitting base-files into
subtarget will provide smaller images due to more specific
distribution of files per subtarget and allow to use default cases
more effectively.

029093a302 bmips: add new target
This target has full device tree support, thus reducing the number of
patches needed for bcm63xx, in which there's a patch for every board.

The intention is to start with a minimal amount of downstream patches and
start upstreaming all of them.

Current status:
 - Enabling EHCI/OHCI on BCM6358 causes a kernel panic.
 - BCM63268 lacks Timer Clocks/Reset support.
 - No PCI/PCIe drivers.
 - No ethernet drivers.
