Ayke van Laethem d3022e7d6e all: add sleep mode to various SPI displays

The API looks like this and is based on the PCA9685 PWM chip:

    Sleep(sleepEnabled bool) error

It will set the LCD panel to a low power state (not displaying any
image) but memory contents will be preserved.

ST7735 driver

There are multiple devices using the ST7735 chip, and there are multiple versions ST7735B, ST7735R & ST7735S. Two apparently identical displays might have different configurations. The most common issues are:

Colors are inverted (black is white and viceversa), invert the colors with display.InvertColors(true)
Colors are not right (red is blue and viceversa, but green is ok), some displays uses BRG instead of RGB for defining colors, change the mode with display.IsBGR(true)
There is noise/snow/confetti in the screen, probably rows and columns offsets are wrong, configure them with st7735.Config{RowOffset:XX, ColumnOffset:YY}

If nothing of the above works, your device may need a different boot-up process.
