rtl8180: fix DMA register are written two times
Hw DMA registers are written in rtl8180_init_hw function. They are also written again just after calling rtl8180_init_hw. There is no point in doing this twice. Remove those redundant register writes from rtl8180_start. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
