ARM: dts: am437x-gp-evm: Add vtt_fixed regulator
The VTT regulator for DDR3 termination on the am437x-gp-evm is controlled by a gpio. It is configured by the bootloader so here we define an always-on, fixed voltage regulator to hold the gpio. Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
