ASoC: rt1320: Change return type of rt1320_t0_load() to void

Clang warns (or errors with CONFIG_WERROR=y / W=e):

  sound/soc/codecs/rt1320-sdw.c:1387:6: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
   1387 |         if (!fw_ready) {
        |             ^~~~~~~~~
  sound/soc/codecs/rt1320-sdw.c:1421:9: note: uninitialized use occurs here
   1421 |         return ret;
        |                ^~~
  sound/soc/codecs/rt1320-sdw.c:1387:2: note: remove the 'if' if its condition is always false
   1387 |         if (!fw_ready) {
        |         ^~~~~~~~~~~~~~~~
   1388 |                 dev_warn(dev, "%s, DSP FW is NOT ready\n", __func__);
        |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   1389 |                 goto _exit_;
        |                 ~~~~~~~~~~~~
   1390 |         }
        |         ~
  sound/soc/codecs/rt1320-sdw.c:1366:9: note: initialize the variable 'ret' to silence this warning
   1366 |         int ret;
        |                ^
        |                 = 0

The return value of rt1320_t0_load() is never actually used, so it can
just be eliminated altogether by returning void, clearing up the
warning.
