The fuse status register provides the values from on-chip
voltage ID efuses programmed at the factory. These values
define the voltage requirements for the chip. u-boot reads
FUSESR and translates the values into the appropriate
commands to set the voltage output value of an external
voltage regulator.

Users migrating Freescale's PowerPC SoC U-Boot code to their custom
board, often overlook the need to execute set_liodns() and
setup_portals() being called by platform files.
So Move set_liodns() and setup_portals() to common u-boot boot
sequence

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

find_tlb_idx() is called in board_early_init_r() on multiple boards.
The return value is not checked before being used to disable a TLB.
In normal case the return value wouldn't be -1. In case of a mis-
configuration during porting to a new board, checking the return value
may be helpful to reveal some user errors.
