arm64: dts: ti: k3-am625-verdin: fix SD1 driver strength
Set SD1 interface driver strength to 33 Ohm (that is the minimum value we can configure), considering the additional 22 Ohm series resistor on the Development Carrier board we get to 55 Ohm that is the closest value to the ideal 50 Ohm we can get. Upstream-Status: Pending Initial DTS to be used for bring-up an validation of the V1.0 design, we'll decide on the step forward to mainline this once the bring-up and validation will be done. Signed-off-by: Francesco Dolcini <francesco.dolcini@toradex.com>
