Thanks for spotting this.

These values were taken from the BSP* code, which was tested
the most (and apparently works), I tend to leave the value as is
and fixup the comment.

Thanks!

* The BSP does not use L2X0 driver, instead, it contains 'L2CC'
  driver with these values hard-coded. But nowadays the L2CC driver
  is unneeded as L2X0 supports PL310 controllers.
