Thomas Huth 6b591ad613 tests/prom-env: Enable the test for the sun4u machine, too
The 32-bit TCG bug has been fixed a while ago, so we can enable
this test for sparc64 now, too. Unfortunately, OpenBIOS does not
work with the sun4v machine anymore (it needs to catch up with the
improved emulation), so we can only enable this test for the sun4u
machine right now.

* This test is used to check that some Open Firmware based machines (i.e.
* OpenBIOS or SLOF) can be started successfully in TCG mode. To do this, we
* first put some Forth code into the "boot-command" Open Firmware environment
* variable. This Forth code writes a well-known magic value to a known location
* in memory. Then we start the guest so that the firmware can boot and finally
* run the Forth code.
* The testing code here then can finally check whether the value has been
* successfully written into the guest memory.
