There are 8 cs35l41 speaker amplifier connected to TDM
in my Xiaomi Mi Pad 5 Pro tablet. In this case, it's necessary
to set 12288000 (48000 * 32 * 8) clk freq for it.

rate=48000, slot_width=32, slots=8.

This is a valid clocking configuration. 12.288 MHz is already available in cs35l41_pll_sysclk[] as well.
Values for fs1 and fs2 are not required because cs35l41_dai_set_sysclk() will use hardcoded values for freq > 6.144 MHz.
