[PATCH] i2c: i2c-s3c2410: fix runtime PM cleanup

[Jiawen Liu]

Keep clock enabled until adapter teardown.

The remove path disables the controller clock before unregistering the
I2C adapter, so adapter teardown can run after the hardware clock has
already been turned off.

Move I2C teardown before clock release (pm_runtime_disable,
clk_unprepare) in s3c24xx_i2c_remove.
