rtl8180: add rtl8187se HW initialization
This patch adds few functions that initializes extra stuff that is present only in rtl8187se HW, and it modify the existing HW initialization function where necessary Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
