tests/gem_workarounds: Skip write only registers
We have no means to check write only registers as
this would need access through context image. For now we
know that cnl has a one such register, 0xe5f0 which is used
to set WaForceContextSaveRestoreNonCoherent:cnl. By inspecting
the context image without and with workaround applied:
0x0000a840: 0x0000e5f0 0xffff0800
0x0000a840: 0x0000e5f0 0xffff0820
we can conclude that the workaround setup is working right
in this particular case.
Add a write only list and add register 0xe5f0 into this list.
This is a temporary solution until a more capable context image
checker emerges.
