ASoC: soc-core: Fix regression causing sysfs entries to disappear
The allocation order of things in soc_new_pcm_runtime was changed to move the device_register before the allocation of the rtd structure. This was to allow the rtd allocation to be managed by devm. However currently the sysfs entries are added by device_register and their visibility depends on variables within the rtd structure, this causes the pmdown_time and dapm_widgets sysfs entries to be missing for all rtds. Correct this issue by manually calling device_add_groups after the appropriate information is available.
