Subject: ASoC: nau8825: fix invalid configuration in Pre-Scalar of FLL

From: John Hsu <KCHSU0@nuvoton.com>


[ Upstream commit a1792cda51300e15b03549cccf0b09f3be82e697 ]

The clk_ref_div is not configured in the correct position of the
register. The patch fixes that clk_ref_div, Pre-Scalar, is assigned
the wrong value.
