Nishanth Menon 2b6bcce32c hwrng: ks-sa - fix division by zero in ks_sa_rng_init ...

[ Upstream commit 612b1dfeb4 ]

Fix division by zero in ks_sa_rng_init caused by missing clock
pointer initialization. The clk_get_rate() call is performed on
an uninitialized clk pointer, resulting in division by zero when
calculating delay values.

Add clock initialization code before using the clock.

Fixes: 6d01d8511d ("hwrng: ks-sa - Add minimum sleep time before ready-polling")
