Subject: [PATCH] spi: sprd: adi: Use IS_ENABLED() to validate configs

If the Spreadtrum wachdog is loaded as a module, we still need set default
watchdog reboot mode in case the rebooting is caused by watchdog. But now
we can not set the watchdog reboot mode by using '#ifdef' to validate
the watchdog configuration, thus we can change to use IS_ENABLED() to
fix this issue.
