Subject: [PATCH 6/14] arch/mips/pmc-sierra/yosemite/setup.c: delete double assignment

From: Julia Lawall <julia@...u.dk>

Delete successive assignments to the same location.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

This change also makes the variable cpu_clock_freq be not used in the
current file.  If this is the correct change to plat_time_init, then
perhaps the declaration of that variable should be moved elsewhere, or the
variable should be deleted completely.
