Keyguard: Can't enter PIN code when setting the SIM and PIN lock issue

By original design, after unlock SIM PIN, SIM card's state is READY and it
will invoke resetStateLocked() to inflate KeyguardHostView. So there is
only one view be created in mSecurityViewContainer.

Roll back previous solution.
Don't set mSimState before handleSimStateChange() and don't judge
isSecure() to be consistent with the original design.

frameworks: add persistent notification when USB OTG is connected

Tapping the notification will take the user into Storage settings, and
highlight the 'Unmount' option.
