soc/intel/meteorlake: Make use of is_devfn_enabled() function 

1. Replace all pcidev_path_on_root() and is_dev_enabled()
functions combination with is_devfn_enabled().
2. Remove unused local variable of device structure type
(struct device *).
3. Replace pcidev_path_on_root() and dev->enabled check with
is_devfn_enabled() call.

TEST=Able to build and boot without any regression seen on MTL.
