hv: Remove CONFIG_PARTITION_MODE used to compile out irq enable/disable 

ACRN uses CONFIG_PARTITION_MODE  macro to compile out CPU_IRQ_ENABLE/DISABLE
APIs. With vector remapping enabled for pre-launched VMs, this is of no use.
And for VMs with LAPIC pass-thru, interrupts stay disabled in vmexit loop
with the help of is_lapic_pt() API.
