Uwe Kleine-König 0e1816d8c2 pwm: fsl-ftm: Handle clk_get_rate() returning 0 ...

[ Upstream commit 928446a5302eee30ebb32075c0db5dda5a138fb7 ]

Considering that the driver doesn't enable the used clocks (and also
that clk_get_rate() returns 0 if CONFIG_HAVE_CLK is unset) better check
the return value of clk_get_rate() for being non-zero before dividing by
it.
