Tony Lindgren aa6eee8bd0 hwrng: omap3-rom - Call clk_disable_unprepare() on exit only if not idled ...

[ Upstream commit eaecce12f5f0d2c35d278e41e1bc4522393861ab ]

When unloading omap3-rom-rng, we'll get the following:

WARNING: CPU: 0 PID: 100 at drivers/clk/clk.c:948 clk_core_disable

This is because the clock may be already disabled by omap3_rom_rng_idle().
Let's fix the issue by checking for rng_idle on exit.
