ARM: at91: sama5: add common environment for QSPI

Browse source 
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.
