ASoC: txx9: Replace tasklet with work
The tasklet is an old API that should be deprecated, usually can be
converted to another decent API. In ASoC TXx9 ACLC driver, a tasklet
is still used for offloading the hardware reset function. It can be
achieved gracefully with a work queued, too.
This patch replaces the tasklet usage in TXx9 ACLC driver with a
simple work. The conversion is fairly straightforward.
