hw/input/tsc2005: Fix -Wchar-subscripts warning in tsc2005_txrx()
Check the function index is in range and use an unsigned
variable to avoid the following warning with GCC 13.2.0:
[666/5358] Compiling C object libcommon.fa.p/hw_input_tsc2005.c.o
hw/input/tsc2005.c: In function 'tsc2005_timer_tick':
hw/input/tsc2005.c:416:26: warning: array subscript has type 'char' [-Wchar-subscripts]
416 | s->dav |= mode_regs[s->function];
