[PATCH 2/3] arm64: dts: juno: Add ETR SMMU power domain

[Robin Murphy]

It is not at all clear from the documentation, but straightforward to
determine in practice, that the ETR SMMU is actually in the DEBUGSYS
power domain. Add that to the DT so that anyone brave enough to enable
said SMMU doesn't experience a system lockup on boot, especially a
sneaky one which goes away as soon as you connect an external debugger
to have a look at where it's stuck (thus powering up DEBUGSYS by other
means and allowing it to make progress again before actually halting...)
