Remove redundant click action from date & time container layout

Unlike AOSP, CyanogenMod provides separate actions for both the clock
and date & time views in the expanded notification area. AOSP has a
single action for both views.

This commit removes the redundant AOSP click action completely. In
addition, the clock and date views are modified to occupy the entire
height of the layout to increase the clickable area.
