arm64: dts: hisilicon: hikey970: Add SD and WiFi supporthikey970_sd
Add SD and WiFi support for HiKey970 board based on HI3670 SoC. Due to the absence of the PMIC driver, fixed regulators are sourced to make the driver working. Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
