hv: add function to set AP entry

Browse Source 
With reset_vcpu_regs as pre-condition, we only need to set
cs_selector and cs_base for AP.

We call set_ap_entry in two places:
 1. When emulation AP SIPI
 2. When sos BSP resume from S3. The BSP is resumed to real
    mode with entry set to wakeup_vec. We call set_ap_entry
    API here with entry twisted from wakeup_vec.
