ASoC: tas2764: Add post reset delays

Browse Source 
[ Upstream commit cd10bb89b0d57bca98eb75e0444854a1c129a14e ]

Make sure there is at least 1 ms delay from reset to first command as
is specified in the datasheet. This is a fix similar to commit
307f31452078 ("ASoC: tas2770: Insert post reset delay").

Fixes: 827ed8a0fa ("ASoC: tas2764: Add the driver for the TAS2764")
