chosen node.

Add __dt_setup_arch() that can be called to load a builtin DT.
Additionally we add a macro to allow loading a specific symbol
from the __dtb_* section.

This patch makes IRQ_DOMAIN usable on MIPS.  It uses an ugly workaround
to preserve current behaviour so that MIPS has time to add irq_domain
registration to the irq controller drivers.  The workaround will be
removed in Linux v3.6

These files are not modules, but were including module.h only for
EXPORT_SYMBOL and/or THIS_MODULE.  Now that we have the lightweight
export.h, use it in these kinds of cases.

This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument.  Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.

The physical address is never used by the device tree code when
allocating memory for unflattening.  Change the architecture's alloc
hook to return the virutal address instead.

The totalsize field was be32. And the reserve bootmem would cause failure.
