econet: replace pending patches with upstream backports

The EN751221 clock/reset bindings and driver, along with the PCI bridge
window fix, have all been accepted upstream. Replace the downstream
patches with the exact versions merged upstream and add the kernel
version tag:

  910: dt-bindings: clock, reset: Add econet EN751221           (v7.1, 35af99f7482673)
  911: clk: airoha: Add econet EN751221 clock/reset support     (v7.1, d8b034525fd954)
  913: PCI: Prevent assignment to unsupported bridge windows    (v7.1, 92427ab4378faa)

Refresh the patches as a result.
