Revert omap443x_cpu_control: Do not change the dependent voltage

I did not read and did not notice that the code was changing the
main voltage, not the dependent voltage.
omap443x_cpu_control: Unflip GPU min/max voltages
omap443x_cpu_control: Rejigger GPU opp modification

We cannot modify omap_volt_data for the core domain because devices
other than the GPU require voltages in that data. We can only add extra
entries - so only support one extra voltage for modification of the
fastest GPU OPP.
omap443x_cpu_control: Use the correct GPU clock
omap443x_cpu_control: Fix formatting of output of tweaked OPP tables
omap443x_cpu_control: Add locking comment
omap443x_cpu_control: Compile fixes
omap443x_cpu_control: More Compile Fixes
omap443x_cpu_control: Fix GPU voltage check

I forgot about units.
omap443x_cpu_control: Fix typo
omap443x_cpu_control: Do not use OMAP44XX_CONTROL_FUSE_CORE_OPP100OV

The registers pointed to by OMAP44XX_CONTROL_FUSE_CORE_OPP100OV do not
exist on OMAP4430.
omap4430_cpu_control: Remove bootup printing of GPU OPP

This is not necessary now that we have sysfs interfaces to get the GPU
