[ALSA] remove redundent assignment to the ac97 device structure
AC97 Codec Don't use dev.platform_data to store a reference to the containing ac97_t structure. Such assignment is redundent since we can deduce the ac97_t structure location from the contained device structure. This sets platform_data free for other purposes.
