Schematic indicates GPIO5_7 is to be used for VTT regulator control rather than GPIO0_21 so modify enable_vtt_regulator to reflect this. Without this some boards will experience DDR3 corruption and fail to boot. Signed-off-by: Dave Gerlach <d-gerlach@ti.com> [trini: Rework patch against mainline] Signed-off-by: Tom Rini <trini@ti.com>
