ARM: dts: imx7d-sdb: Pass 'enable-gpios' and 'power-supply' properties

Browse source 
Currently the LCD is turned on thanks to the bootloader initialization.

In order to make the kernel to turn on the LCD on is own, pass the
'enable-gpios' and 'power-supply' properties.

Also, the GPIO1_IO01 is not used as PWM functionality on this board. It is
connected to the PWREN pin of connector J14 and has a GPIO function, so
remove the PWM1 node and change the GPIO1_IO01 IOMUX to GPIO function.
