On usual A64 board design the power of HDMI controller is connected to DLDO1 of the AXP803 PMIC. If this regulator is shut down, the HDMI output will be blank. Therefore the simplefb driver should keep this regulator on. Add the regulator to all currently available A64 boards' simplefb_hdmi device node.
