* CONFIG_UG9664HSWAG01_POWER
* If the hardware supports a controllable OLED a power supply, this

* Required LCD driver settings:
* CONFIG_LCD_UG9664HSWAG01 - Enable UG-9664HSWAG01 support
* CONFIG_LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be accepted.

* Description:
* Initialize the UG-9664HSWAG01 video hardware. The initial state of the
* OLED is fully initialized, display memory cleared, and the OLED ready
* to use, but with the power setting at 0 (full off == sleep mode).
*
* Input Parameters:
*
* spi - A reference to the SPI driver instance.
* devno - A value in the range of 0 through CONFIG_UG9664HSWAG01_NINTERFACES-1.
* This allows support for multiple OLED devices.
*
* Returned Value:
*
* On success, this function returns a reference to the LCD object for
* the specified OLED. NULL is returned on any failure.
