Use the same memory layout as we use for the NAND boot on the other boards.
QSPI flashes are present on the following boards: sama5d2_xplained RevB: 32 Mbyte flash (mx25l3273fm2i-08g) sama5d2_xplained RevC: 8 Mbyte flash (sst26vf064b-104i/sn) sama5d27_som1_ek: 8 Mbyte flash (sst26vf064b-104i/sn) sama5d2_ptc_ek: 8 Mbyte flash (sst26vf064b-104i/sn)
The 8 Mbyte limit is enough to cope with the memory layout used in the NAND boot. rootfs exceeds the 8 Mbyte limit and will stay in eMMC in the sama5d2_xplained case. The final scope is to use a single memory layout for all boot medias.
