bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set
In 35fc84f, bootm was refactored so plain 'bootm' and 'bootm <subcommand>' shared a common implementation. The 'bootm ramdisk' command implementation is now part of the common implementation but not invoke by plain 'bootm' since the original implementation never did ramdisk relocation. Instead, ramdisk relocation happened in image_setup_linux() which is typically called during the OS portion of 'bootm'.
On ARM, parameters to the Linux kernel can either be passed by FDT or ATAGS. When using FDT, image_setup_linux() is called which also triggers ramdisk relocation. When using ATAGS, image_setup_linux() is _not_ called because it mostly does FDT setup.
Instead of calling image_setup_linux() in both FDT and ATAGS cases, include BOOTM_STATE_RAMDISK in the requested states during a plain 'bootm' if CONFIG_SYS_BOOT_RAMDISK_HIGH is set and remove the ramdisk relocation from image_setup_linux(). This causes ramdisk relocation to happen on any system where CONFIG_SYS_BOOT_RAMDISK_HIGH regardless of the OS being booted. Also remove IMAGE_ENABLE_RAMDISK_HIGH as it was only used by the now-removed code from image_setup_linux().

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().
