Dave Gerlach cd8341b7eb ARM: AM43xx: GP-EVM: Correct GPIO used for VTT regulator control
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.
