HV: specify dispatch hypercall for sos or trusty

Changes:

- In current design, the hypercall is only allowed calling from SOS or
trusty VM, so separate the trusty hypercalls from dispatch_hypercall().
The vm parameter which referenced by hcall_xxx() should be SOS VM;

- do not inject #UD for hypercalls from non-SOS, just return -ENODEV;

Tracked-On: #3214
