Subject: [PATCH 1/2] ASoC: tlv320aic3x: Don't sync first two registers from register cache

There is no need to sync first two registers from cache to hw after a reset.
First one is used to select page for register access and this driver is
normally accessing page 0 only. Second one does a software reset which is
obviously unneeded after hardware or previous software reset command.
