Use cortex-a9 instead of generic
We are going to use now cortex-a9 instead of generic since our device has that
CPU VARIANT and it will probably fix the errors:
the selected processor does not support ARM mode
and the FPU related error which most of us experienced who had
compiled Android Lollipop.
I spotted the changes in Timduru's TF101 device tree which has
the same SoC as our LG Optimus 2X (P990)
