Merge head r233826 through r240095.

Do not swap byte order if we assign default value for intr_cells

Fix argument type for bus_space_map

Merging of projects/armv6, part 4

r233822:
Remove useless and wrong piece of code in fdt_get_range() which i
overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl()
to be cons

r233822:
Remove useless and wrong piece of code in fdt_get_range() which i
overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl()
to be consistent (that is, print start and end *virtual* addresses).

r230560:
Handle "ranges;"
Make fdt_reg_to_rl() responsible for mapping the device memory, instead
on just hoping that there's only one simplebus, and using fdt_immr_va as
the base VA.

r230315
Add a function to get the PA from range, instead of (ab)using
fdt_immr_pa, and use it for the UART driver

Respect phy-handle property in Ethernet nodes of the device tree.

This lets specify whereabouts of the parent PHY for a given MAC node
(and get rid of ugly kludges in mge(4) and tsec(4)).

Fix OF_finddevice error return value in case of FDT.

According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.

This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
-1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
as well.

on a board, the interrupt pin alone is not unique.

Import the common Flattened Device Tree infrastructure.

o fdtbus(4) - the main abstract bus driver for all FDT-compliant systems. This
is a direct replacement for the many incompatible bus drivers grouping
integrated peripherals on embedded platforms (like obio(4), ocpbus(4) etc.)

o simplebus(4) - bus driver representing ePAPR style 'simple-bus' node, which
is an umbrella device for most of the integrated peripherals on a typical
system-on-chip device.
