lcd: move platform-specific structs to their own headers
common/lcd code is full of platform-specific code and definitions, which ideally should reside with the respective driver code. Take a step towards that goal by moving platform-specific structs from lcd.h to their own header files. The structs for the generic case (the #else for all the platform-specific cases) is retained in lcd.h as the default case.
