UBI/cfi-mtd: Fix mtd name for multiple chips
On platforms with multiple NOR chips, currently only the first one
can be selected using the "ubi part" command. This patch fixes this
problem by using different names for the NOR "mtd devices".
It also changes the name of the NOR MTD device from "cfi-mtd" to
"norX" (X indexing the device numer) to better match the mtdparts
defaults.

UBIFS: add R/O compatibility
Now UBIFS is supported by u-boot. If we ever decide to change the
media format, then people will have to upgrade their u-boots to
mount new format images. However, very often it is possible to
preserve R/O forward-compatibility, even though the write
forward-compatibility is not preserved.
This patch introduces a new super-block field which stores the
R/O compatibility version.

... and to make it useful for NAND chips as well, we should also remove now
unrelated CONFIG_JFFS2_NAND. Note that struct part_info etc is in
jffs2/load_kernel.h which is a bit misleading filename for that purpose,

include/ns16550.h: Unify structure declaration for registers
Instead of special casing the different access patterns, use common
code with light macros sprinkled in to accomodate for the different
layouts of the register structure.
Note that this also changes the types of the registers for the
"positively packed (>1)" cases. As the registers truly are unsigned
chars, this is surely the Right Thing, but it is a semantic change.
Note that for this case depending on the endianness on the bus, we may
see a change of behaviour.
