[PATCH RESEND v5 2/2] ASoC: mxs-saif: Remove platform data

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

All MXS users have been converted to device tree and the board files have been
removed.

No need to keep platform data in the driver.

Changes since v4:
- Rebased against fix/mxs branch and fix file removal
Changes since v3:
- Remove pdev->id check
Changes since v2:
- Also remove 'if (np)' as dt is the only probing mechanism.
Changes since v1:
- Also remove mxs_saif_platform_data and sound/saif.h, which was used only
to include mxs_saif_platform_data definition.
