[PATCH 4/4] ASoC: loongson: fix compile testing on 32-bit

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

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.

Fixes: d24028606e764 ("ASoC: loongson: Add Loongson ASoC Sound Card Support")
