Ronald Wahl 11ace0214b clk: at91: Fix division by zero in PLL recalc_rate() ...

commit 0f5cb0e622 upstream.

Commit a982e45dc1 ("clk: at91: PLL recalc_rate() now using cached MUL
and DIV values") removed a check that prevents a division by zero. This
now causes a stacktrace when booting the kernel on a at91 platform if
the PLL DIV register contains zero. This commit reintroduces this check.
