57a3a62265 hw/intc: ibex_timer: Convert the timer to use RISC-V CPU GPIO lines
Instead of using riscv_cpu_update_mip() let's instead use the new RISC-V
CPU GPIO lines to set the timer MIP bits.

df41cbd6bf hw/timer: Initial commit of Ibex Timer
Add support for the Ibex timer. This is used with the RISC-V
mtime/mtimecmp similar to the SiFive CLINT.

We currently don't support changing the prescale or the timervalue.
