- Fix NAND pinctrl by adding missing nand_rb0 pin.
- Disable unused pcie_phy to suppress probe warning.
- Re-enable pcie_phy on S400 board to keep PCIe working.
All changes have been tested on real hardware.

The nand_all_pins pinctrl node was missing the nand_rb0 (ready/busy)
pin description, which is required for NAND controller operation.
Add it to the pinmux list.

Set the pcie_phy node to "disabled" as it is not used on some boards
and should be enabled per-board when necessary.
This change suppresses the deferred probe warning:
platform ff644000.phy: deferred probe pending: (reason unknown)

The meson-axg dtsi now disables pcie_phy by default, so enable it
for the s400 board to support PCIe functionality.
