[PATCH 2/3] watchdog: txx9wdt: Add missing clock (un)prepare calls for CCF

[Geert Uytterhoeven <geert@linux-m68k.org>]

While the custom minimal TXx9 clock implementation doesn't need or use
clock (un)prepare calls (they are dummies if !CONFIG_HAVE_CLK_PREPARE),
they are mandatory when using the Common Clock Framework.

Hence add them, to prepare for the advent of CCF.
