Revert "Update headers from Dazozzo's U8815 device tree"

This reverts commit 604f71db286a4cc35d87f92595f1f6d2e331a703.

Revert back to old headers to fix problems with EGL on the ics kernel
branch, like:

E/libgenlock(  118): perform_lock_unlock_operation: GENLOCK_IOC_DREADLOCK failed (lockType0x1,err=Invalid argument fd=21)
W/Adreno200-EGLSUB(  118): <GetBackBuffer:2121>: genlock_lock_buffer GENLOCK_WRITE_LOCK failed
E/        (  118): qcomuiClearRegion: eglGetRenderBufferANDROID returned NULL buffer
