Copy the config fragments from the AOSP common kernel android-4.4
branch.  It is becoming possible to run mainline kernels with Android,
but the kernel defconfigs don't work as-is and debugging missing config
options is a pain.  Adding the config fragments into the kernel tree,
makes configuring a mainline kernel as simple as:

  make ARCH=arm multi_v7_defconfig android-base.config android-recommended.config

The following non-upstream config options were removed:

  CONFIG_NETFILTER_XT_MATCH_QTAGUID
  CONFIG_NETFILTER_XT_MATCH_QUOTA2
  CONFIG_NETFILTER_XT_MATCH_QUOTA2_LOG
  CONFIG_PPPOLAC
  CONFIG_PPPOPNS
  CONFIG_SECURITY_PERF_EVENTS_RESTRICT
  CONFIG_USB_CONFIGFS_F_MTP
  CONFIG_USB_CONFIGFS_F_PTP
  CONFIG_USB_CONFIGFS_F_ACC
  CONFIG_USB_CONFIGFS_F_AUDIO_SRC
  CONFIG_USB_CONFIGFS_UEVENT
  CONFIG_INPUT_KEYCHORD
  CONFIG_INPUT_KEYRESET
