arm64: dts: ti: Remove unused and undocumented "ti,(rx|tx)-fifo-depth" properties

Remove "ti,(rx|tx)-fifo-depth" properties which are both unused in the
kernel and undocumented. Most likely they are leftovers from downstream.

There are similar properties, but DP83867_PHYCR_FIFO_DEPTH_4_B_NIB
represents the default value so adding them is not necessary.
