Drivers: hv: Remove deprecated hv_fcopy declarations

There are lingering hv_fcopy declarations which do not have definitions.
The fcopy driver was removed in commit ec314f61 ("Drivers: hv: Remove
fcopy driver").

Therefore, remove the hv_fcopy declarations which are no longer needed
or defined.

Fixes: ec314f61 ("Drivers: hv: Remove fcopy driver")
