ARM: OMAP36xx: hwmod data: fix SmartReflex interface data

Commit d34427267186827dfd62bd8cf726601fffb22534 ("OMAP3: PM: Adding
smartreflex hwmod data") added OMAP36xx-specific SmartReflex IP block
data, but attempted to share the interface data with the OMAP34xx IP
blocks.  This causes some problems - for example, the 36xx IP blocks
won't be registered when the hwmod subsystem is modified to register
links, since they aren't connected to the rest of the data.  So,
modify the OMAP36xx SmartReflex IP block data to use separate
interface data structures from the OMAP34xx SmartReflex IP blocks.
