ASoC: loongson: make loongson-i2s.o a separate module
An object file should not be linked into multiple modules and/or
vmlinux:

scripts/Makefile.build:221: /home/arnd/arm-soc/sound/soc/loongson/Makefile: loongson_i2s.o is added to multiple modules: snd-soc-loongson-i2s-pci snd-soc-loongson-i2s-plat

Change this one to make it a library module with two exported symbols
that will work in any configuration.

ASoC: loongson: Factor out loongson i2s enable clock functions
There are a few i2s clock enable operations in loongson_i2s_set_fmt(),
convert them to simple helper functions called
loongson_i2s_enable_mclk() and loongson_i2s_enable_bclk().

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.
