ARM: OMAP: Allocate McBSP devices dynamically
Based on Chandra's earlier patches in linux-omap tree. Note that omap1_mcbsp_check and omap2_mcbsp_check are no longer needed as there's now omap_mcbsp_check_valid_id() defined. Also some functions can now be marked __init. Signed-off-by: Chandra Shekhar <x0044955@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
