From: Yann Dirson <yann@blade-group.com>

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 features are covered yet either.

Tiny is not really testable by itself today, I played with it using:

 PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-tiny"
 KERNEL_FEATURES_append = "\
  ktypes/base/base.scc \
  features/debug/printk.scc \
  cfg/fs/ext4.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:
- standard                11MB
- tiny                     5MB
- tiny with no defconfig   2.5MB

Changes in v2:
- added explicit CONFIG_PHYLIB and CONFIG_MMC to support empty defconfig
- added CONFIG_SPI_ROCKCHIP
