The pclk is necessary for zx2967 I2S controller. the driver
currently doesn't handle it. This is something we need to fix.
In turn, the driver supports zx296718's I2S controller.
By the way, this patch also change the clock name from tx to wclk
to make it clear.

In zx_i2s_hw_params(), 'format' is initialized and assigned bits based on
params_format, but never used. So remove it.

The macro ZX_SPDIF_CLK_RAT should be 2 instead of 4. With this
fix, we can get correct audio output on HDMI through SPDIF interface.

ZTE ZX SPDIF and I2S drivers can work on not only ZX296702 but also
other ZTE ZX family SoCs like ZX296718, which is an arm64 platform.
Let's make a few renaming and tweak the Kconfig a bit to get the drivers
available for other ZTE ZX platforms.

Use devm_* API to fix leaks in current code.
1. Use devm_kzalloc to fix memory leak for zx_i2s when unload the module.
2. Use devm_snd_soc_register_component to ensure component is unregistered
when unload the module.

Value returned by devm_ioremap_resource() was checked for non-NULL but
devm_ioremap_resource() returns IOMEM_ERR_PTR, not NULL. In case of
error this could lead to dereference of ERR_PTR.
