imx8qxp_mek: Remove SPL watchdog option

Currently the following watchdog error is seen in SPL:

U-Boot SPL 2020.04-00407-g8d5d3bcf3c (Apr 20 2020 - 09:48:09 -0300)
Normal Boot
WDT:   Not found!
...

There is no watchdog driver for i.MX8 at the moment, nor code for
configuring the watchdog in SPL, so remove the CONFIG_SPL_WATCHDOG_SUPPORT
option for now.
