ought, I dropped patches which added RPM to memory
drivers since hardware is always-on and RPM not needed.
- Replaced the "dummy host1x driver" patch with new "Disable unused
host1x hardware" patch, since it's a cleaner solution.

Disable PMC state syncing in order to ensure that we won't break older
kernels once device-trees will be updated with the addition of the power
domains. This also allows to apply device-tree PM patches independently
from the driver patches.
