Subject: ASoC: rt5645: set sel_i2s_pre_div1 to 2

From: Bard Liao <bardliao@realtek.com>


[ Upstream commit 02c5c03283c52157d336abf5e44ffcda10579fbf ]

The i2s clock pre-divider 1 is used for both i2s1 and sysclk.
The i2s1 is usually used for the main i2s and the pre-divider
will be set in hw_params function.

However, if i2s2 is used, the pre-divider is not set in the hw_params
function and the default value of i2s clock pre-divider 1 is too high
for sysclk and DMIC usage. Fix by overriding default divider value to 2.
