ALSA: hda/tas2781: reset the amp before component_add
commit 315deab289924c83ab1ded50022e8db95d6e428b upstream.
Calling component_add starts loading the firmware, the callback function
writes the program to the amplifiers. If the module resets the
amplifiers after component_add, it happens that one of the amplifiers
does not work because the reset and program writing are interleaving.
Call tas2781_reset before component_add to ensure reliable
initialization.
