native: remove QCOM_BSP cruft

* the code that acutally does anything with this code does not exist yet in 4.4 - this is useless and
may be causing problems - remove it
* seems to have been merged accidentally with https://github.com/omnirom/android_frameworks_native/commit/d9805a9a80128421c5fbf5fb8300f0fdf11fd3d1
and ifdeffed in later patches
