The channel num (9 - 15) should not be supported in tdm & daisy chain
mode for there is two dataline, this channel number can't be
symmetrically distributed on two dataline (the first one is fixed to
be 8 channel)
Fixes commit 8d29874365c3 ("MLK-17817-2: ASoC: imx-ak4458: enable 16
channels in TDM mode")

In TDM mode with Daisy Chain enabled (CPLD mode 0x04) DAC1 and DAC2
AK4458 codecs on audio board are able to play 16 channels, so extend
the TDM mode constraint to 16 channels.

When enable DSD for ak4458 with imx8mm platform, in DSD256 mode
the mclk calculated from ak4458_get_mclk_rate is 256fs, but
the codec require the mclk should be 512fs. so just hard code
the clock to be 512fs in DSD mode.

The existing implementation calculates mclk rate as function
of audio sample rate multiplied to multiplier taken from Table 5.
However this is not accurate for Manual Setting Mode - tables 3 & 4 from
AK4458 RM defines rate (LRCK/FS) and frame width (MCLK/16fs..1152fs) ranges
as parameters to calculate mclk frequency. Aside of this - adjust
bclk:mclk ratio from machine driver as function of "compatible" id.

SAI interface now is able to change at runtime the pll parent of the
master clock, so enable both 8k and 11k range of rates for AK codecs.

According to AK4458 RM the MCLK freq need to be set
externaly as function of LRCK frequency. Notice that
multiplier is twice the value shown in RM since SAI
MCLK must be at least double the BCLK.

There is two ak4458 codecs which share some pdn gpio. If assign
the pdn gpio to one codec, will cause the another codec error:
ak4458 1-0012: Unable to sync registers 0x0-0x0. -6
The reason is that if the codec driver is trying to do regcache_sync,
but another codec is resetting the pdn gpio in same time, the
regcache_sync will fail.
So Move the pdn gpio to machine driver, machine driver will
control this gpio for two codecs.

When in TDM mode, change constraints for rate and allow only
rates in [8KHz, 96KHz] due to the limitations of SAI master
clock. If rate is higher than 96KHz, the TX rate cannot be
obtained using only a 49MHz SAI clock.

TDM mode is enabled when "fsl,tdm" property is added in machine
driver dts node. When using TDM mode, SND_SOC_DAIFMT_DSP_B format
is used and the tdm slot_width is set to 32.

For 768kHz sample rate, the codec can't support 64fs mclk, only
can support 32fs mclk, so we can't fix the slot_width to 32, which
is for S32_LE, use params_physical_width(params) to instead of
hard code.
