[PATCH] ASoC: fsl_easrc: force cast 'val1' to u32 for do_div()

[Shengjiu Wang]

Fix below cocci warnings, the real width of val1 is 32bit, so use force
cast to avoid warning.

cocci warnings: (new ones prefixed by >>)
>> sound/soc/fsl/fsl_easrc.c:1999:2-8: WARNING: do_div() does a 64-by-32 division, please consider using div64_u64 instead.
