hv: Cleanup: Remove dead code.

Browse Source 
Now, UOS will use hypercall to init BSP state, we could remove
set_bsp_real_mode_entry() and set_bsp_protect_mode_regs().

For SOS, GDT will inherit from SBL or UEFI. For UOS, DM will
prepare GDT. We don't need hypervisor to prepare GDT for guest.

The entry_addr of vcpu struct could be removed. The guest entry
is set through BSP rip register.

GUEST_CFG_OFFSET is not needed any more after this patchset.
