hv: refine the function pointer type of port I/O request handlers

Browse Source 
In the definition of port i/o handler, struct acrn_vm * pointer
 is redundant as input, as context of acrn_vm is aleady linked
 in struct acrn_vcpu * by vcpu->vm, 'vm' is not required as input.

 this patch removes argument '*vm' from 'io_read_fn_t' &
 'io_write_fn_t', use '*vcpu' for them instead.
