mfd: arizona: Correct calling of runtime_put_sync
[ Upstream commit 6b269a41a4520f7eb639e61a45ebbb9c9267d5e0 ]
Don't call runtime_put_sync when clk32k_ref is ARIZONA_32KZ_MCLK2
as there is no corresponding runtime_get_sync call.
MCLK1 is not in the AoD power domain so if it is used as 32kHz clock
source we need to hold a runtime PM reference to keep the device from
going into low power mode.
Fixes: cdd8da8cc66b ("mfd: arizona: Add gating of external MCLKn clocks")
