cmd/fdt: Make fdt get value endian-safe for single-cell properties
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().
Fixes: bc80295 ("fdt: Add get commands to fdt")
