ramips: add Sanlinking Technologies D240 pinmux quirk
The sd function of the nd_sd group configures two of the groups pins as gpios. The pins are used as PCIe reset/power. Due to the driver load order, the pins are configured way to late if triggered by the sd-card driver. To not introduce another kind of driver load order dependency and configure the pins as early as possible, means during pinmux driver load. Signed-off-by: Mathias Kresin <dev@kresin.me>
