ARM: OMAP: mcbsp: Fix possible memory corruption
Commits 09d28d ("ARM: OMAP: mcbsp: Start generalize omap2_mcbsp_set_clks_src")
and 7bc0c4 ("ARM: OMAP: mcbsp: Start generalize signal muxing functions")
incorrectly set two struct omap_mcbsp_platform_data fields after
omap_device_build_ss and kfree calls.
Fix this by moving these pdata assignments before those calls.
