ASoC: loongson: fix compile testing on 32-bit
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.

ASoC: loongson: fix unused PM function warning
Build testing without CONFIG_PM_SLEEP causes a warning:

sound/soc/loongson/loongson_i2s.c:246:12: error: unused function 'i2s_suspend' [-Werror,-Wunused-function]
sound/soc/loongson/loongson_i2s.c:255:12: error: unused function 'i2s_resume' [-Werror,-Wunused-function]

Use the modern SYSTEM_SLEEP_PM_OPS() instead of the old one to avoid this.

ASoC: Add support for Loongson I2S controller
Loongson I2S controller is found on 7axxx/2kxxx chips from loongson,
it is a PCI device with two private DMA controllers, one for playback,
the other for capture.

The driver supports the use of DTS or ACPI to describe device resources.
