fbdev: atyfb: Remove unused clock determination
Just below the removed lines par->clk_wr_offset is hard coded to 3 so
there is no use in determining a different clock just to then ignore it
anyway. This also removes the only I/O port use remaining in the driver
allowing it to be built without CONFIG_HAS_IOPORT.
