commit a14bc107edd0c108bda2245e50daa22f91c95d20 upstream.

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'
