Subject: [PATCH] SystemUI: add burnIn protection

Devices with AMOLED display suffer from
status-bar's notification items and nagivation bar's software keys
causing permanent burn-ins when used long-term.

Moving all items in the area
both horizontally and vertically workarounds this problem.

jrizzoli: integrate with runtime cmsdk preference

Linux4: removed toggle from settings - the burnIn protection is always
enabled if the corresponding AOSP overlay is set to true
