In this function, the variable 'dev' is assigned to '&pdev->dev',
but in the following code, all the assignments to 'struce device'
are used '&pdev->dev' instead of 'dev',except 'zx_tdm->dev'.
So,the variable 'dev' in this function is redundant and can be
replaced by '&pdev->dev' as elsewhere.

zx-tdm driver sets the DAI driver definitions with the format bits
wrongly set with SNDRV_PCM_FORMAT_*, instead of SNDRV_PCM_FMTBIT_*.
This patch corrects the definitions.
Spotted by a sparse warning:

The audio parameter setup in zx_i2s_hw_params() works fine with 32-bit
samples, but for 16-bit ones, all we can hear is harsh noises.
As suggested by vendor driver code, DMA burst size and TS width should
always be 32 bits, no matter audio sample is 16-bit or 32-bit.
Follow the suggestion above to fix the harsh noise issue seen with
16-bit audio samples.

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.
