- lvgl init was already done in `lvgl_gui` component (in `lvgl.c`), and this method called `lvgl_lcd_hal_init()`

dd2f5f0ca8 Workaround for 240x240 screen rotation issue 
- The st7789 controller is for 320x240 screen, but the screen is 240x240, therefore when screen is rotated, an offset of 80 must be added depending on the orientation
- Also added some comments
