hv: vtd: allocate drhd_dev_scope based on board file

Browse Source 
Determine the size of drhd_dev_scope based on DRHD_MAX_DEVSCOPE_COUNT
in board file instead of hardcoding. The current default value 16 will
be used if it is not defined in board file to keep compatibility, a
warning will be raised in this case.
