[PATCH 2/5] arm64: tegra: Add actmon information

[Johnny Liu]

An activity monitor (actmon) is used to measure the device runtime
utilization to help drive software power management policies.

Configuration of actmon is under the host1x address space. Therefore,
add the actmon aperture under the host1x.

All unit actmons for host1x clients share the same actmon clock source
from host1x. Therefore, add the clock phandle in host1x.
