ENGR00125045 MX53: Adjust VDDGP voltage setting
1. Adjust VDDGP for 1GHZ as 1.15v
2. Adjust VDDGP for 800MHZ as 1.05v
3. Not all current MX53 boards can run up to 1GHZ. So one limitation is
added into clock.c to limit 1GHZ working point. To enable 1GHZ
working point in kernel, please increase the GP voltage and type the
command "clk core 1000" in uboot console to switch CPU core to 1GHZ.
This limitation will be removed after all boards support 1GHZ.
