Currently on OMAP4/5 platforms, many kernel drivers are dependent
upon the bootloaders for mux, dpll and clock configurations.
This should not be the case and bootloaders should set only the
minimum required for the uboot functionality and kernel boot.

Note that this is going to break the kernel drivers. But this
is the only way to get things fixed in the kernel.
