Review comment:
       Hi @gustavonihei I´ve just tried enabling both ST7735 and ST7789 and it 
configured and compiled NuttX without any problems. But when I run the fb 
example application it took the resolution of ST7735 instead of ST7789 because 
of those #ifdefs 
https://github.com/michallenc/incubator-nuttx/blob/st77xx/drivers/lcd/st77xx.c#L97.
   
   I think the changes I did would not allow to use both 7735 and 7789 at the 
same time (because of resolution and also some other stuffs that are under 
ifdefs). It is a question whether we want to keep that option of using both 
controllers (I don´t know how much are two different displays used, haven´t 
seen much of those options myself) or to keep those controllers under one file.
