In altr_i2c_remove(), the controller clock is disabled before
i2c_del_adapter() is called. This leaves the adapter teardown running
without the hardware clock, which can cause issues during adapter
removal.

Move the clk_disable_unprepare() call after i2c_del_adapter() to ensure
the adapter is removed while the clock is still available.
