[PATCH] PCI: j721e: Fix incorrect max_lanes for J7200

[Takuma Fujiwara]

The PCIe Controller in the J7200 SoC supports a 4-lane configuration.
However, j7200_pcie_rc_data and j7200_pcie_ep_data incorrectly set
.max_lanes = 2, limiting operation to fewer lanes than the hardware
supports.

Set .max_lanes = 4 for both j7200_pcie_rc_data and j7200_pcie_ep_data to
match the hardware capability.

See J7200 Technical Reference Manual (SPRUIU1D), section 12.2.3.1.1
for further details: https://www.ti.com/lit/pdf/spruiu1d
