Shiji Yang c77913be5b ramips: correct the PCIe port number for Zbtlink ZBT-WE1326
MT7621 gets a new PCIe driver in the 5.15+ kernel. Allocating wrong PCIe
port will cause the PCIe NIC to not work properly. This commit fixes
the wrong port numbers on Zbtlink ZBT-WE1326.

According to the bootlog, MT7612E (5 GHz) is connected to pcie1, and
MT7603E (2 GHz) is connected to pcie2:
[4.197658] mt7621-pci 1e140000.pcie: pcie0 no card, disable it (RST & CLK)
[4.204609] mt7621-pci 1e140000.pcie: PCIE1 enabled
[4.209476] mt7621-pci 1e140000.pcie: PCIE2 enabled
...
[4.307988] pci 0000:01:00.0: [14c3:7662] type 00 class 0x028000
[4.367206] pci 0000:02:00.0: [14c3:7603] type 00 class 0x028000
