Ak4458 can't support DSD512 format, but ak4497 can, so add
a new enum variable (enum ak4458_type) in ak4458_drvdata to
distinguish these two platforms.
Ak4497 has two kinds of DSD input pin, it can be selected by
the dsd-path property from DT.
In hw_params(), bit clock is calculated according to different
DSD format (DSD64, DSD128, DSD256, DSD512), then registers
are configured.

It supports I2S, DSD and TDM modes with 24 or 32 bit MSB
or 16, 24, 32 LSB formats. Its datasheet is available here:
