Apologies, Will check and add it back.

In v3 as well, the hs_phy_irq is before qusb2_phy interrupt:

This is reordering the targets based on interrupts they have. I put it 
in one commit because splitting this into multiple patches breaks one 
thing or other. Also once I am defining permutations, I have to group 
targets into these combinations in the same patch. I know this is a big 
commit but it solves the interrupt cleanup and defines a way for future 
targets.
