Commit 18cfd9429d8a82c49add8f3ca9d366599bfcac45 simplified the S500 SMP
code by removing a loop for pen_release in owl_secondary_boot().
Since then it is only calling owl_v7_invalidate_l1() before branching to
secondary_startup().
The owl_v7_invalidate_l1() assembler function is superfluous, too.
Therefore drop owl_secondary_boot() and use secondary_boot() directly.

The S500 SoC can start secondary CPUs without busy-looping for pen_release,
so simplify the SMP code compared to the LeMaker kernel tree.
