Subject: [PATCH] cpufreq: SPEAr: Make read-only array sys_clk_src static

Don't populate the read-only array sys_clk_src on the stack but instead
make it static and add in a missing const. Also makes the object code a
little smaller.

sys_clk_src[2] isn't used and could be deleted with the
pclk indices changed.

Dunno what happened to the > 500000000 && != 600000000 range.
