ASoC: tas2562: Fix default digital volume

Browse Source 
The tas2562 digital volume is spread over four registers and is implemented
as lookups into a table so the driver stores the value for the userspace
control in the driver data. This defaults to 0 due to kzalloc() but the
register default is 0x40400000 which maps onto something a bit over the
largest value defined in the lookup table. While it's not an exact match
update the default to the largest value, avoiding user surprise due to a
sudden change on first write.
