omap3: Add basic support for 720MHz part

This patch adds support for new speed enhanced parts with ARM
and IVA running at 720MHz and 520MHz respectively. These parts
can be probed at run-time by reading PRODID.SKUID[3:0] at
0x4830A20C [1].

This patch specifically does following:
 * Detect devices capable of 720MHz.
 * Add new OPP
 * Ensure that OPP is conditionally enabled.
 * Check for presence of IVA before attempting to enable
   the corresponding OPP.
