lcd: split splash code into its own function
lcd_logo() currently performs tasks well beyond just displaying the logo. It has code which displays splash image, it has logic which determines when the different display features are displayed, and it is coupled with the lcd console because it holds the responsibility of returning the lcd console base address. Make lcd_logo() just about the logo by: * Moving splash image display code into a dedicated function * Moving the logic regarding when various features are displayed to lcd_clear() (which is arguably not the correct name for housing such code either, but it is currently the most fitting location code wise) * Move the responsibility of setting the console base address to lcd_clear() too.
