arm64: dts: imx8mp: Switch WiFI enable signal to mmc-pwrseq-simple on i.MX8MP DHCOM SoM
The reset-gpio is connected to WL_REG_EN signal of the WiFi MAC, the mmc-pwrseq-simple driver is better suited to operate this signal as it is tied to the slot instead of the MAC, and it can enable the MAC before the brcmfmac driver binds to it. Make use of the MMC power sequencer. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
