drm/xe/pf: Simplify IS_SRIOV_PF macro
Instead of two having variants of the IS_SRIOV_PF macro, move the
CONFIG_PCI_IOV check to the xe_device_is_sriov_pf() function and
let the compiler optimize that. This will help us drop poor man's
type check of the macro parameter that fails on const xe pointer.
