[U-Boot] [PATCH v1 2/3] wdt: Timeout better to be in microseconds

[Andy Shevchenko]

Timeout in some abstract ticks is not what we are applying to get
deterministic behaviour.

Convert name to show explicitly that we are using microseconds (for
watchdog it's more than precise).

No functional change intended.
