[PATCH v1 1/1] watchdog: sp805: Fix kernel doc description

[Andy Shevchenko]

Kernel doc validation script is not happy

  CHECK   .../sp805_wdt.c
  .../sp805_wdt.c:73: warning: Function parameter or member 'rate' not described in 'sp805_wdt'

Fix this by describing rate parameter.

While at it, mark clk one optional.
