[PATCH v2] watchdog: Enable COMPILE_TEST where possible

From: Guenter Roeck
Date: Sat Dec 31 2016 - 14:14:27 EST

Building all watchdog drivers is all but impossible since many depend
on platforms which are not enabled by test builds. Add dependency on
COMPILE_TEST where possible to improve the situation.

Signed-off-by: Guenter Roeck <linux@xxxxxxxxxxxx>
---
v2: More extensive tests found some resulting build errors, where the
driver compiles but fails to link with missing symbols. Exclude
the affected drivers.
