This way we only have entries in the device tree for disks that actually
exist. A slight complication is that disks may be attached to LPARs
at runtime.

Now we will only have entries in the device tree for the actual existing
devices (including their OS/400 properties). This way viotape.c gets
all the information about the devices from the device tree.

Remove the iSeries initrd logic, instead just store the initrd location and
size in the device tree so generic code can do the rest for us.
The iSeries code had a "feature" which the generic code lacks, ie. if the
compressed initrd is bigger than the configured ram disk size, we make
the ram disk size bigger. That's bogus, as the compressed size of the initrd
tells us nothing about how big the ram disk needs to be. If the ram disk
isn't big enough you just need to make CONFIG_BLK_DEV_RAM_SIZE larger.

This driver uses the hvc_console.c infrastructure that is used by the
pSeries virtual and RTAS consoles. This will allow us to make viocons.c
obsolete and is another step along the way to a combined kernel (as
viocons could not coexist with CONFIG_VT).

No one outside platforms/iseries needs ItExtVpdPanel anymore, so move
it in there. It used to be needed by lparcfg, and so was exported, but
isn't needed anymore, so unexport it.

e2a() was formally used by lparcfg, and so had to be exported, but isn't
anymore, so don't.
e2a() and strne2a() can both be static, and __init.
And e2a can be made much more concise if we use x ... y case labels, while
we're there add support for lower case letters.

The ASCII -> EBCDIC functions, e2a() and strne2a() are now only used in
dt.c, so move them in there.

This also consolidates the initial bits of lparcfg_data() and adds the
partition number to the iSeries flattened device tree.

Consolidate the vio device node creation. Make some parameters const.
Make a few more things __initdata. Get the device_type strings out of
the device tree blob.

This actually simplies things as we just figure out how much space we
used at the end and adjust klimit then.

First we capture all the strings from dt.c statically by noting that gcc
puts them in a special section of their own. Idea from Michael Ellerman.
Then we move the flattened device tree to klimit.
Still to come, making the values blob grow as needed.
