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.
