rockchip: rk3568-radxa-e25: Enable pcie3x1 node
Enable mini PCIe slot, pcie3x1 node, now that the PCIe PHY driver
support bifurcation.
A pinctrl is assigned for reset-gpios or the device may freeze running
pci enum and nothing is connected to the mini PCIe slot.
Also drop the AHCI_PCI Kconfig option as this option is not required for
a functional M.2 SATA drive slot.
