Subject: [PATCH v2 04/16] clk: remove unnecessary !core->parents conditional

This if-block has been here since the introduction of the common
clock framework.  Now no clock drivers are statically initialized.
core->parent is always NULL at this point.  Drop the redundant
check and the confusing comment.
