AIA extends the width of all IRQ CSRs to 64bit even
in 32bit systems by adding missing half CSRs.

This seems to be missed while adding support for
virtual IRQs. The whole logic seems to be correct
except the width of the masks.

Fixes: 1697837ed9 ("target/riscv: Add M-mode virtual interrupt and IRQ filtering support.")
Fixes: 40336d5b1d ("target/riscv: Add HS-mode virtual interrupt and IRQ filtering support.")
