dt-bindings: PCI: qcom,pcie-sm8350: Drop redundant 'oneOf' sub-schema

The first entry in the 'oneOf' schema doesn't work because the top
level schema requires exactly 8 interrupt entries. The 2nd entry is just
redundant with the top level. Since 1 entry appears to have been a
mistake, let's just drop the entire 'oneOf' rather than reworking the
top-level to allow 1 entry.
