[PATCH 3/8] ARM: OMAP2+: timer: Add comment on timer clk parenting

[Joel Fernandes]

Add a comment describing the state of system timer clock parenting.  The code
following the comment should be deleted once all platforms can do DT boot, and
specially should not be executed for DT platforms once we can specify default
clock parents through DT.
