Subject: [PATCH v4 5/5] arm: qcom: dts: Enable NAND node on IPQ8064 AP148 platform

Enable the NAND controller node on the AP148 platform. Provide pinmux
information.

v4:
- Move bias-disable out of mux and create a separate group for it.
- Place the dma node inside soc node and give the full path with address.

v3, v2, v1:
- No changes
