as3525v2: make sure volume is normal by writing Audioset2 register

If the bit 6 is set volume is much lower, without writing it explicitely
it is undefined.
According to linux sources this bit is related to mixer.

Initialize Audioset2 with low power 'hph' (probably headphones) quality,
as I couldn't make a difference with 'high quality' setting.
