sandbox: add concept of sandbox state

The state exists through the life of U-Boot. It can be adjusted by command
line options and perhaps later through a config file.  It is available to
U-Boot through state_...() calls (within sandbox code).

The primary purpose of this is to contain the "hardware" state.  It should
only be used by sandbox internal code.

integrator: remove fragile delay loop from PCI code

The reference implementation of the PCI initialization code almost
everywhere contain this fragile loop of "a few usecs", and its
use of volatile variables to delay a number of bus cycles is indeed
uncertain.

Reading the manual "Integrator/AP Users Guide", page 5-15 it is
clearly stated:

"Wait until 230ms after the end of the reset period before
accessing V360EPC internal registers. The V360EPC supports the
use of a serial configuration PROM and the software must wait for
the device to detect the absence of this PROM before accessing any
registers. The required delay is a function of the PCI Clock, but
at the lower frequency (25MHz) is 230ms".

So let's simply wait 230ms per the spec.

This solves the compilation error that looked like this:

always copied into oobbuf and never appended to datbuf.  Within U-Boot only
the nand_dump function (for the dump nand subcommand) was expecting the OOB
data to only be appended to datbuf.  So we now change nand_dump to not
malloc extra space, correct the comment about datbuf and OOB data and switch
the pointer to oobbuf before printing.

It breaks boards that currently rely on soft-ecc, as pointed out here:

The reverted patch should be resubmitted with documentation, and with the

start by looking at what NAND driver the board selects, and whether
