Gdisp lld driver corrections

Corrections to Nokia gdisp driver
- Fix for the application calling the unsupported gdispSetOrientation
and gdispSetPower
- Implemented full backlight control (on/off only currently)

Corrections to the Ili9320 driver
- Fix for the application calling the unsupported gdispSetOrientation
- Fix for initialisation of the backlight
- Fix for backlight when using display low power modes.
