arm64: dts: imx8m{m,n}-venice-gw7902: add SDR50/SDR104 SDIO support for wifi
The GW7902 has a Murata LBEE5H 802.11abgnac / BT5 module based on the Cypress CYW43455 which supports SDR50/SDR104. Add dt pinctrl for the 100mhz and 200mhz states to support SDR50/SDR104. While at it add the dt node for the CYW43455 wifi. Signed-off-by: Tim Harvey <tharvey@gateworks.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
