On a Raspberry Pi 2 disagreements on cell endianness can be observed:

U-Boot> fdt print /soc/gpio@7e200000 phandle phandle = <0x0000000d> U-Boot> fdt get value myvar /soc/gpio@7e200000 phandle; printenv myvar myvar=0x0D000000

Fix this by always treating the pointer as BE and converting it in fdt_value_setenv(), like its counterpart fdt_parse_prop() already does.

Consistently use fdt32_t, fdt32_to_cpu() and cpu_to_fdt32().
