Subject: [PATCH v3 1/3] ASoC: codecs: tlv320dac33: Remove unused struct tlv320dac33_platform_data and header file tlv320dac33-plat.h

Remove the tlv320dac33_platform_data struct and header file
tlv320dac33-plat.h as they are not used anywhere in the kernel
or outside this driver.

Signed-off-by: Alex Tran <alex.t.tran@...il.com>
