Chen Ni 7f39ab718c watchdog: sa1100: Fix PTR_ERR_OR_ZERO() vs NULL check in sa1100dog_probe() 
[ Upstream commit 413bf4e857 ]

devm_ioremap() doesn't return error pointers, it returns NULL on error.
Update the check accordingly.

Fixes: e86bd43bcf ("watchdog: sa1100: use platform device registration")
