reset: a10sr: add missing of_match_table reference

The driver defined of_device_id table but did not use it with
of_match_table.  This prevents usual matching via devicetree and causes
a W=1 warning:

  drivers/reset/reset-a10sr.c:111:34: warning:
    ‘a10sr_reset_of_match’ defined but not used [-Wunused-const-variable=]
