colibri_vf: synchronize/improve memory options
Synchronize initramfs related configuration options and improve
memory layout. The memory layout with an offset of 16MiB allows
to boot bigger kernels. With AUTO_ZRELADDR, which is pretty much
the standard nowadays, the kernel relacates itself to PC masked
with 0xf8000000 plus a text offset of 0x8000 (hence 0x80008000 for
Vybrid). With a 16MiB offset from the start of memory and a 16MiB
distance to the device-tree, we allow kernel up to ~16MiB.
