[PATCH] arm: iproc: Add higher speed configurations

Add support for 1.3GHz, 1.35GHz and 1.4GHz parts. This is based on
equivalent code in Broadcom's LDK 5.0.6.

As Broadcom are currently migrating users to the BCM58525BB1KF14G part
I suspect others may want this. In our case because we wanted to still
run at 1.2GHz we also had to set CONFIG_ARMCLK to 1200.
