Well, I defined the binding such that both omap2 and omap3
can use the same compatible "ti,omap2-hsmmc" since there is
no difference in the way they are defined or handled. If thats
confusing, I can have separate compatibles.
Btw, I guess we do the same with a few other re-used IPs as well,
I just checked and mcpsi does the same.
