bus: ti-sysc: Fix uninitialized framedonetv_irq
[ Upstream commit 085bc0e576a4bf53b67a917c54908f299a2fb949 ]
We are currently only setting the framedonetv_irq disabled for the SoCs
that don't have it. But we are never setting it enabled for the SoCs that
have it. Let's initialized it to true by default.
