2012-06-15arm: tegra: xmm: removing L3 state transitionVinayak Pane
Remove L3 state from xmm power driver. New usb phy code allows pm state transition L0->L2 and L2->L0. When the system goes in LP0/LP1 suspend then the modem power state is kept at L2 and bus state in suspend controlled by PMC. At system resume the hsic bus is given back to USB.

XMM modem first enumeration has timing requirement, so khubd should perform enum within 1 second.
