acrn hypervisor not handle the handle_reset_reg_read properly #8688

we find when we add the reboot=p,c,panic_w to enable the cold reset in normal reboot and warm reset when kernel panic happen, we can see only cold reboot available, while the default reboot is always warm reset.

We need the warm reset to do memory dump to help debug, as hypervisor will only return the ~0x0,
