arm64: dts: ti: k3-am625-verdin: remove SD1 speed limitation
Remove 100MHz speed limitation on SD_1 interface, it was initially
needed because of an additional 22 ohm resistor on the SD clock on the
SoM, after replacing it with a 0 ohm the SD_1 interface is running fine
even at 200MHz.
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.
