* sde_get_dt_props - allocate and return prop counts, exists & values arrays
* @np - device node
* @prop_max - <BLK>_PROP_MAX enum, this will be number of values allocated
* @sde_prop - pointer to prop table
* @prop_size - size of prop table
* @off_count - pointer to callers off_count
*
* @Returns - valid pointer or -ve error code (can never return NULL)
* If a non-NULL off_count pointer is given, the value it points to will be
* updated with the number of elements in the offset array (entry 0 in table).
* Caller MUST free this object using sde_put_dt_props after parsing values.
