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.
