This patch provides "standard" and "tiny" BSP.

There is still much work to be done in dispatching feature to individual
scc files - the more boards we can support the better it will get.
Not all SoC/board features are covered yet either (esp. Wifi/Bluetooth and
audio jack), and properly-woking HDMI still needs patches.

Tiny is not fully testable by itself, it can be minimally booted with
serial console (though still missing CONFIG_MULTIUSER for serial getty,
and CONFIG_INOTIFY_USER for proper udev operation) using:

PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-tiny"
KERNEL_FEATURES_append = "\
ktypes/base/base.scc \
features/debug/printk.scc \
cfg/fs/ext4.scc \
cfg/8250.scc \
"

Such a tiny build is still using mainline defconfig with lots of hardware
features, and the kernel can be slimmed down even more by using:

KBUILD_DEFCONFIG = ""

Kernel weight using default configurations:
- standard 11MB
- tiny 5MB
- tiny with no defconfig 2.5MB

It looks to me as though the BRCMFMAC kernel config option needs to be enabled
to support the AP6256S? I don't see that being enabled, does it end up being
pulled in by default or as a result of the above two settings?
