On the first generation of Allwinner SoCs (A10-A31), the i2s controller was
using the MCLK as BCLK parent. However, this changed since the introduction
of the A83t and BCLK now uses the module clock as its parent.
Let's introduce a hook to get the parent rate and use that in our divider
calculations.

The two main generations of our I2S controller require a slightly different
format configuration, mostly because of a quite different register layout
and some additional registers being needed on the newer generation.
This used to be controlled through a bunch of booleans, however this proved
to be quite impractical, especially since a bunch of SoCs forgot to set
those parameters and therefore were broken from that point of view.

The MCLK divider calculation is currently computing the ideal divider using
the oversample rate, the sample rate and the parent rate.
However, since we have access to the frequency is supposed to be running at
already, and as it turns out we're using it to compute the oversample rate,
we can just use the ratio between the parent rate and the MCLK rate to
simplify a bit the formula.

The BCLK divider should be calculated using the parameters that actually
make the BCLK rate: the number of channels, the sampling rate and the
sample width.
We've been using the oversample_rate previously because in the former SoCs,
the BCLK's parent is MCLK, which in turn is being used to generate the
oversample rate, so we end up with something like this:
oversample = mclk_rate / sampling_rate
bclk_div = oversample / word_size / channels
So, bclk_div = mclk_rate / sampling_rate / word_size / channels.
And this is actually better, since the oversampling ratio only plays a role
because the MCLK is its parent, not because of what BCLK is supposed to be.
Furthermore, that assumption of MCLK being the parent has been broken on
newer SoCs, so let's use the proper formula, and have the parent rate as an
argument.

The current computation for the SR (sample resolution) and the WSS (word
slot size) register parameters is based on a switch returning the matching
parameters for a given params width.
Later SoCs (A83t, H3, A64) changed that calculation, which was loosely the
same with an offset. Therefore, an offset was added to adjust those
parameters.
However, the calculation is a bit less trivial than initially thought.
Indeed, while we assumed that SR and WSS were always the same, on older
SoCs, SR will max at 24 (since those SoCs do not support 32 bits formats),
but the word size can be 32.
Newer SoCs can also support a much larger range (8 bits to 32 bits, by
increments of 4) of size than the older SoCs could.
Finally, the A64 and A83t were never adjusted to have that offset in the
first place, and were therefore broken from that point of view.
In order to fix all those issues, let's introduce two functions, get_wss
and get_sr, with their respective implementations for all the SoCs
supported so far.

When any of the DAI hardware configuration callbacks (.hw_param,
.set_fmt, .set_sysclk) fails, there is no explanation about why it
failed. This is particularly confusing for .hw_param, which covers
many parameters of the DAI. Telling the users what parameter isn't
supported, and what the requested value was goes a long way for
developers trying to combine sun4i-i2s with external codecs.
This patch adds dev_err calls explaining what isn't supported or
failed, and what the value was. sun4i_i2s_set_clk_rate()'s first
parameter was changed to a struct snd_soc_dai *dai, so we can
