hw/display/tcx: Add missing fall through comments
When building with GCC9 using CFLAG -Wimplicit-fallthrough=2 we get:
hw/display/tcx.c: In function ‘tcx_dac_writel’:
hw/display/tcx.c:453:26: error: this statement may fall through [-Werror=implicit-fallthrough=]
453 | s->dac_index = (s->dac_index + 1) & 0xff; /* Index autoincrement */
| ~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
hw/display/tcx.c:454:9: note: here
454 | default:
| ^~~~~~~
hw/display/tcx.c: In function ‘tcx_dac_readl’:
hw/display/tcx.c:412:22: error: this statement may fall through [-Werror=implicit-fallthrough=]
412 | s->dac_index = (s->dac_index + 1) & 0xff; /* Index autoincrement */
| ~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
hw/display/tcx.c:413:5: note: here
413 | default:
| ^~~~~~~
cc1: all warnings being treated as errors
Give a hint to GCC by adding the missing fall through comments.
