Stefan Wahren 4810cce029 watchdog: bcm2835_wdt: Fix WDIOC_SETTIMEOUT handling
[ Upstream commit f33f5b1fd1be5f5106d16f831309648cb0f1c31d ]

Users report about the unexpected behavior for setting timeouts above
15 sec on Raspberry Pi. According to watchdog-api.rst the ioctl
WDIOC_SETTIMEOUT shouldn't fail because of hardware limitations.
But looking at the code shows that max_timeout based on the
register value PM_WDOG_TIME_SET, which is the maximum.

Since 664a39236e ("watchdog: Introduce hardware maximum heartbeat
in watchdog core") the watchdog core is able to handle this problem.

This fix has been tested with watchdog-test from selftests.
