ASoC: codecs: wsa884x: disable runtime PM on unbind

Browse Source 
Probe enables runtime PM but nothing disables it on unbind. The pending
autosuspend then runs wsa884x_runtime_suspend() after the devm-managed
regmap is freed, and dereferences NULL:

  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020
  pc : regcache_cache_only+0x18/0x80
  lr : wsa884x_runtime_suspend+0x24/0x40 [snd_soc_wsa884x]

Use devm_pm_runtime_enable() so runtime PM is disabled before the regmap
is freed.
