Title: some little correction in SSD1289 driver

- clear function: moved call to reset_viewport after aquire_bus, so LCD receive the new viewport
- control function: added call to acquire_bus and release_bus

Sorry I'm pedantic with indenting code, sometime there are 4 spaces and sometime one tab. I changed some rows. :)
