lcd: allow overriding lcd_get_size()
Remove the redundant lcd_line_length initialisation which
sneaked in when an earlier version of the patch of commit
6d330719 has been rebased.
Some lcd drivers need to setup lcd_line_length not from the
panel_info parameters but by different means. Make the
lcd_get_size() weak to allow setting lcd_line_length in
a driver specific way.
