c7e7948924 arm64: xilinx: Setup default number of chipselects for zcu100
There is only one chipselect on each connector.
Define it directly in board dts file.
There should be an option to use more chipselects via gpios.

Card detect bit was broken on revA and it is working fine with revC
board that's why this property can be removed.

767afebbcd arm64: zynqmp: Enable cadence WDT for zcu100
Enable watchdog on zcu100 to make sure if there is a bug in the u-boot
there is proper reset.
Watchdog expires and PMU fw is informed and based on setting proper
action is taken.

The patch is enabling reset-on-timeout feature and also fixing fixed
clock rate for watchdog where 100MHz is max (and also default) clock value.
