configs: add a DT-enabled Raspberry Pi defconfig
This is an example of a Device-Tree-enabled Raspberry Pi defconfig. We have to use a 3.18-based kernel for that, but there are a few limitations: - we can not use the minimalist RPi defconfig bundled with the kernel, namely bcmrpi_quick_defconfig, because it is not DT-enabled, and sets CONFIG_ARM_PATCH_PHYS_VIRT to 'n', which prompts a value for CONFIG_PHYS_OFFSET, as it as no default for the bcm familly; - most importantly, the rpi-3.18.y branch is constantly rebased, so there is no guarantee that the sha1 I use today will still be usable in the long term. Using the name of hte branch is not better either. So, we bundle our own DT-enabled linux defconfig that is based on bcmrpi_quick_defconfig, with just CONFIG_ARM_PATCH_PHYS_VIRT set and the Device TRee enabled. Signed-off-by: "Yann E.
