The 'screen_bits' LCD initializer bit array is only required if
CONFIG_INIT_LCD is enabled, otherwise we get the following warning:
arch/m68k/68000/screen.h:4:22: warning: 'screen_bits' defined but not used [-Wunused-variable]
static unsigned char screen_bits[] = {
^~~~~~~~~~~
Make the inclusion of 'screen_bits' conditional on CONFIG_INIT_LCD.

The kernel test robot reports that the "screen_bits" splash screen data
is missing for the dragen platform:
arch/m68k/68000/dragen2.c:73:16: error: 'screen_bits' undeclared (first use in this function)
73 | LSSA = (long) screen_bits;
| ^~~~~~~~~~~
arch/m68k/68000/dragen2.c:73:16: note: each undeclared identifier is reported only once for each function it appears in
Digging around a bit I found the screen_bits data structure was originally
in a screen.h file that was generated from a screen.xbm file. That was
removed in commit 0c0e6db806 ("m68k: drop unused parts of 68VZ328
Makefile").
Other splash screen initializers for 68000 targets are kept here as the
C data structures so lets do the same for this one. Add the missing
screen.h file and include it in the dragen specific startup code.
