msm8x60: Disable 2D GPU cores

The 2D GPUs have been broken since cyanogen backported the newer kgsl drivers from CAF jb_2.6, as he forgot to fix the regulators for the 2D GPUs. No modern device has 2D GPUs, and nobody has noticed that they've been broken for a long time, so just remove them completely.
