r8152: move some functions from probe to open 

Add up method for rtl_ops and asign relative functions. Move
clear_bp() and hw_phy_cfg() from init method to up method of rtl_ops.
Call rtl_ops.up() for ndo_open() and rtl_ops.down for ndo_stop().

Replace allocating the memory in probe() with in ndo_open().
