This patch adds reset-on-timeout to FPD WDT which will trigger an
interrupt to PMU when watchdog expiry happens and PMU takes the
necessary action. If this property is not enabled, reason will not be
known when watchdog expiry happens.
This patch also modifies the default timeout to 60 seconds. Reason is
that if u-boot enables WDT, it will set the timeout to 10 seconds and
this is not enough to boot till Linux and start the WDT application in
Linux. 60 seconds is the maximum safest value to boot till Linux and
start the WDT application.
Users need to change this timeout value to fit their needs.

This chip is on the board but handling should be done via firmware not
via Linux driver. Changing status property to keep it in the tree to
describe it instead of removing this node completely.

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.

dtc is showing some warnings and this change was also done in
the Linux kernel as "Input: gpio-keys - clean up device tree binding
example"
with this fragment in commit message
"Drop #address-cells and #size-cells, which are not required by the
gpio-keys binding documentation, as button sub-nodes are not devices."

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

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.
