Subject: [PATCH v7 2/3] dt-bindings: arm: rockchip: Add Orange Pi 5b enum to Orange Pi 5 entry

This extends the Xunlong Orange Pi 5 device tree binding
with an enum for the Orange Pi 5b, which is implemented
before the device tree.

How does this board differ from the original Orange Pi 5?
  - the Orange Pi 5 has a M.2 NVMe M-key PCI 2.0x1
    slot (hooked to combphy0_ps) whereas the Orange Pi 5b uses combphy0_ps
    for the WiFi.
  - The Orange Pi 5 with the M.2 socket has a regulator defined hooked to
    "GPIO0_C5" (i.e. PCIE_PWREN_H) whereas the Orange Pi 5B has GPIO0_C5
    hooked to BT_WAKE_HOST.
  - builtin eMMC storage
  - no SPI NOR flash (u-boot, preboot etc. initiates
      from within the eMMC
      storage)
  - ap6275p Wifi module (like the Orange Pi 5 Plus)
  - builtin BlueTooth module
