MIPS: qi_lb60: remove custom u-boot.lds script

Browse source 
Remove the board specific linker script. It is not
needed anymore, the unified MIPS linker script can
be used instead.

The qi_lb60 target produces a slightly different
image after the change than before. The value of
'num_got_entries' symbol is different:

This is caused by the different placement of the
'__got_start' and '__got_end' symbols between the
board specific scrip and the unified script.

  board specific script:

        __got_start = .;
        .got  : { *(.got) }
        __got_end = .;

  unified script:
        .got  : {
                __got_start = .;
                *(.got)
                __got_end = .;
        }

Despite this difference, the resulting images are
functionally identical.
