The cpu.c and cache-l2x0.c files hold only two or three simple
functions each, and they are all called from the machine
descriptors, so we can just move them all into the same file
for simplicity and consistency.

As the ux500 id code is basically a standalone driver, we can move it
out of the arch code into drivers/soc/ux500.

This is a user-visible change, as it moves all the devices in sysfs
from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a
separate device.

Originally the idea was to put all on-chip devices under the soc node,
and ux500 was the first platform to have this device, but later platforms
almost all didn't follow that pattern, so this makes the platform do
the same thing as everyone else.

Since the platform is really obsolete now, I am optimistic that nothing
will break after moving the devices around.

As the SoC driver no longer has access to the private header files,
I'm changing the code to instead look up the address of the backupram
from devicetree, which is a good idea anyway.

Finally, having a separate Kconfig symbol means the driver is now
optional and could even be a loadable module rather than always being
built-in if we allowed that for soc_device.

ux500_setup_id is currently called from u8500_map_io(), which is
really early, but nothing relies on the ID any more, other than
a printk message that is not really all that important to
have early during boot.

If we move the call to ux500_setup_id() into ux500_soc_device_init(),
that file becomes usuable almost entirely standalone, and we can kill
off the u8500_map_io() callback as it just does the default
debug_ll_io_init() now.

Instead of the pen grab/release, just point the ROM to

last static mapping and get both CPUs booting properly.
