ASoC: loongson: fix compile testing on 32-bit

Browse Source 
DIV_ROUND_CLOSEST() does not work on 64-bit variables when building for
a 32-bit target:

ld.lld: error: undefined symbol: __udivdi3
>>> referenced by loongson_i2s.c
>>>               sound/soc/loongson/loongson_i2s.o:(loongson_i2s_hw_params) in archive vmlinux.a

Use DIV_ROUND_CLOSEST_ULL() instead.
