machine: Rename rockchip.inc include file to rk3066.inc

This include file is used by rk3066 and rk3188 based devices. So this
is better to rename it rk3066.inc and to create another include file
rk3188.inc which simply includes it. In that way, we have one include
file for each SoC and it reduces confusions.
