soc/amd/stoneyridge: use is_dev_enabled(DEV_PTR())

Since we have chipset devicetrees for both SoCs supported by the
Stoneyridge code, we can use the DEV_PTR macro instead of using
pcidev_path_on_root to get the device struct pointer. We can also use
the is_dev_enabled function instead of checking the value of the enabled
element of the device struct directly.
