arm_fpga: Remove bogus timer initialisation

The arm_fpga platform code contains an dubious line to initialise some
timer. On closer inspection this turn out to be bogus, as this was only
needed on some special (older) FPGA board, and is actually not needed on
the current model. Also the base address was wrong anyways.

Remove the code entirely.
