Temp: Workaround the delay in stopping the bootanimation

There's a race condition somewhere in the display subsys making
the bootanim sometimes take a long time to stop. (It actually does
stop, but gets stuck shutting down, and never changes state). So
force it down so that its dependencies can proceed until the
actual error is fixed

Remove redundant headers

The HAL makefiles now fetch these directly from the kernel source
tree
