Fix fallthrough warnings in sh776fb.c:
../drivers/video/fbdev/sh7760fb.c: In function 'sh7760fb_get_color_info':
../drivers/video/fbdev/sh7760fb.c:138:23: warning: this statement may fall through [-Wimplicit-fallthrough=]
138 | lgray = 1;
../drivers/video/fbdev/sh7760fb.c:143:23: warning: this statement may fall through [-Wimplicit-fallthrough=]
143 | lgray = 1;
Just document the current state of code execution/flow.
