hw/pxa2xx_timer: Explicitly mark fallthroughs
Explicitly mark the fallthroughs as intentional in the code
pattern where we gradually increment an index before falling
into the code to read/write that array entry:
case THINGY_3: idx++;
case THINGY_2: idx++;
case THINGY_1: idx++;
case THINGY_0: return s->thingy[idx];
This makes static analysers happy.
