    keyguard: fix layout for sw320dp devices

    800x480px dpi devices have less screen space than the xhdpi devices
    Google designed the layout for and the layout needs adjustment.

    - Reduce the lockscreen security container size such that the clock
      widget has enough space to display its content.
    - In the SIM PIN/PUK view, Google put an empty widget on top, but
      we don't have space for that, increase its size such that the
      widget practically disappears.

    This should not have any effect on devices with larger screens.

    Ported from cm-10.2.
    * Removed invalid mdpi layout leftover from framework-res
    * Fix keyguard for mdpi devices too

    keyguard: fix-fix layout for sw320dp devices

    Default values need to be defined in sw360dp or larger devices will
    pick up sw320dp values automatically.

    On the maguro device the keyguard isn't properly centered.
