[vim3] Fix GIC config.
Incorrectly ipi_base was set to 0, which caused some of the non-secure
IPIs to end up in the range 8-15. That range is commonly for secure IPI.
The side effect was that the HALT IPI (3) with an IPI base of 5, would
result in 8, and just vanish.
IPI Base is an escape hatch for non conforming firmware if the secure
firmware uses other IRQs.
