clk: mediatek: mt7988-infracfg: fix clocks for 2nd PCIe port

Browse Source 
Due to what seems to be an undocumented oddity in MediaTek's MT7988
SoC design the CLK_INFRA_PCIE_PERI_26M_CK_P2 clock requires
CLK_INFRA_PCIE_PERI_26M_CK_P3 to be enabled.

This currently leads to PCIe port 2 not working in Linux.

Reflect the apparent relationship in the clk driver to make sure PCIe
port 2 of the MT7988 SoC works.
