rtl8187: move pll reset at start out of ANAPARAM write
On 8187B start, comment about pll reset, and move it out of ANAPARAM write sequence, so that code is more readable. Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
