soc/intel/icelake: Use devfn_disable() function for XDCI
Use devfn_disable() for disabling a PCI device rather than
using `dev->enabled = 0`.
Also, use is_devfn_enabled() to get the device current state prior
updating the FSP-S UPD for XDCI.
TEST=FSP-S disabled XDCI when `xdci_can_enable` returns 0 and XDCI
is disabled at PCI enumeration `PCI: 00:14.1: enabled 0`.
