Same as the commit 518de86b (ASoC: tegra: register 'platform' from DAIs,
get rid of pdev). It makes davinci-pcm not a platform_driver but helper
to register "platform", so that the platform_device for davinci-pcm can
be saved completely.

Remove the feature to configure the CLKR/FSR mux on McBSP port with 6pin
configuration.
When moving to devicetree these callback can no longer be used in a clean
way anymore.
If a board require to change the 6pin port to work in 4pin setup it needs
to set up the mux in the board file.
For OMAP2/3:
u32 devconf0;

/* McBSP1 CLKR/FSR signal to be connected to CLKX/FSX pin */
devconf0 = omap_ctrl_readl(OMAP2_CONTROL_DEVCONF0);
devconf0 |=  OMAP2_MCBSP1_CLKR_MASK | OMAP2_MCBSP1_FSR_MASK;
omap_ctrl_writel(devconf0, OMAP2_CONTROL_DEVCONF0);

For OMAP4:
u32 mcbsp_pad;

/* McBSP4 CLKR/FSR signal to be connected to CLKX/FSX pin */
mcbsp_pad = omap4_ctrl_pad_readl(OMAP2_CONTROL_DEVCONF0);
mcbsp_pad |=  ((1 << 31) | (1 << 30));
omap4_ctrl_pad_writel(mcbsp_pad, OMAP2_CONTROL_DEVCONF0);

In case when the kernel is booted with DT blob the pinctrl-single will be
provided as soon as it is enabled on the platform.
