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.
