f22347346e hv: Remove separate interrupt routine for pre-launched VMs
As vector re-mapping is enabled for pre-launched/partition mode VMs,
there is no more need for separate interrupt routine i.e.
partition_mode_dispatch_interrupt.

5b795a3312 hv: add the support of vector remapping for pre-launched VMs
For pre-launched VMs MSI/MSI-x configuration writes are not intercepted by ACRN.
It is pass-thru and interrupts land in ACRN and the guest vector is injected into
the VM's vLAPIC. With this patch, ACRN intercepts MSI/MSI-x config writes and take
the code path to remap interrupt vector/APIC ID as it does for SOS/UOS.
