`checkpatch.pl` requires that dts sources are indented with tabs,
fix all the spaces that slipped in while checkpatch wasn't watching.

There is currently not an in-tree Zephyr board which enables the
wdt_xilinx_axi driver as part of its standard configuration. (It can be
enabled fairly easily with the Digilent Arty board, but that requires
modifying the ARM-provided FPGA block design in Vivado and rebuilding
the FPGA image, so it cannot be used with the default FPGA image.)
Add a build_all target to provide build coverage for this driver.
