auxdisplay: linedisp: Group display drivers together
For better usability group the display drivers together in Kconfig. With this we will have the following sections: - Character LCD - Samsung KS0108 LCD controller - Single character line display - Character LCD with non-conforming interface Keep Makefile entries sorted alphabetically. While at it, drop redundant 'default n' entries. Tested-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
