ar71xx: fix kernel Oops in at803x_link_change_notify

Browse source 
r45954 ("ar71xx: fix 100/10mbps ethernet link issues on mynet range
extender") introduced a pdata based modification of the tx_clk_dly. But it
was not checked if pdata actually existed. This caused a page fault on all
devices which didn't have at803x_platform_data specified for an at803x
based device.
