Update config.xml

Building was giving these errors:
device/samsung/d2-common/overlay/frameworks/base/core/res/res/values/config.xml:312: error: Resource at config_disableHomeUnlockSetting appears in overlay but not in the base package; use <add-resource> to add.
device/samsung/d2-common/overlay/frameworks/base/core/res/res/values/config.xml:336: error: Resource at config_fastChargePath appears in overlay but not in the base package; use <add-resource> to add.

So I had to comment out lines 
312 (config_disableHomeUnlockSetting)
and 336 (config_fastChargePath)
to get it to build for d2spr.
