ALC5659 supports maximum data length of 24-bit. Currently driver supports
S24_LE which is a 32-bit container with valid data in [23:0] and 0s in MSB.
S24_3LE is not commonly used and is hard to find audio streams with this
format. Also many SoC HW do not support S24_LE and S32_LE is used in
general. The 24-bit data can be represented in S32_LE [31:8] and 0s are
padded in LSB.
This patch adds S32_LE to ALC5659 driver and data length for this is set
to 24 as per codec's maximum data length support. This helps to play
24-bit audio, packed in S32_LE, on HW which do not support S24_LE.

Removing Bard(bardliao@realtek.com) from "to" list since I am getting
undelivered message.
Oder,
Please add right folks as you feel necessary. Thanks.
