db-88f6820-gp.h: Load data blobs into lower memory

By default on this platform, u-boot loads data into high memory in the range of 0x7Fxxxxxx, which generates a data abort when the kernel tries to read it. Config the u-boot environment to load the device tree and initrd image into lower memory to make them accessible to the kernel.
