PATCH v2 1/1 ARM: at91: sama5: change the environment address to 0x6000

As sama5 board has 32k sram size, so the at91bootstrap and spl for sama5 boards is bigger than 16k (0x4000). That will overlap the U-Boot environment. So I move environment to 0x6000. And reduce its size as well.

Following shows the size of the spl binaries (v2015.04 vs v2015.07):

% ls v2015.04/*spi*spl.bin -l | awk '{print $5,$(NF)}' 15540 v2015.04/at91sam9n12ek_spiflash_defconfig_u-boot-spl.bin 15704 v2015.04/at91sam9x5ek_spiflash_defconfig_u-boot-spl.bin 16064 v2015.04/sama5d3xek_spiflash_defconfig_u-boot-spl.bin 16304 v2015.04/sama5d4ek_spiflash_defconfig_u-boot-spl.bin 16304 v2015.04/sama5d4_xplained_spiflash_defconfig_u-boot-spl.bin
