Subject: [PATCH 5.6 24/38] ASoC: tas2562: Fixed incorrect amp_level setting.

From: Jonghwan Choi <charlie.jh@...aocorp.com>

commit eedf8a126629bf9db8ad3a2a5dc9dc1798fb2302 upstream.

According to the tas2562 datasheet,the bits[5:1] represents the amp_level value.
So to set the amp_level value correctly,the shift value should be set to 1.
