arm: tegra: comms: hsic first enum issue with flight mode off
After flight mode on/off, EHCI phy power and modem power on sequences
not correct. For first enumeration HSIC phy should be power and then
modem needs to be powered before sending any hub events. Also
corrected initial state for ipc_ap_wake_state.
