Subject: [PATCH] drm/panel: olimex-lcd-olinuxino: select CRC32

Fix the following build/link error by adding a dependency on the CRC32
routines:

  ld: drivers/gpu/drm/panel/panel-olimex-lcd-olinuxino.o: in function `lcd_olinuxino_probe':
  panel-olimex-lcd-olinuxino.c:(.text+0x303): undefined reference to `crc32_le'

Fixes: 17fd7a9d324fd ("drm/panel: Add support for Olimex LCD-OLinuXino panel")
