display5: wdt: Enable WDT support (both SPL and u-boot)

Test case:

The fitImage gets corrupted:

truncate -c -s 3M fitImage
run tftp_mmc_fitImg
setenv boot_os y
reset

[board shall hang in SPL with
"Trying to boot from MMC1" information]

Then after X seconds WDT is causing board to reset. After N boot attempts
we enter recovery mode.
