hv: unify the function pointer assignment

Browse Source 
Assign function pointer without the unary & operator.

Take 'register_io_emulation_handler' as an example:
void register_io_emulation_handler(struct acrn_vm *vm,
                const struct vm_io_range *range,
                io_read_fn_t io_read_fn_ptr,
                io_write_fn_t io_write_fn_ptr)

The last two parameters are function pointer.
Sometimes we use function designator directly, while sometimes
with the unary & operator, as shown below.
 - without &
   register_io_emulation_handler(vm, &range, vuart_read, vuart_write);
 - with &
   register_io_emulation_handler(vm, &pci_cfg_range,
                   &pci_cfg_io_read, &pci_cfg_io_write);

To unify the coding style, we will go with the first way.
