cmd_part: add partition-related command

part uuid mmc 0:1

part uuid mmc 0:1 uuid

known devices for something bootable, and then wants the kernel to
use the same partition as the root device, e.g.:

disk: get_device_and_partition() "auto" partition and cleanup

Rework get_device_and_partition() to:
a) Implement a new partition ID of "auto", which requests that U-Boot
   search for the first "bootable" partition, and fall back to the first
   valid partition if none is found. This way, users don't need to
   specify an explicit partition in their commands.
b) Make use of get_device().
c) Add parameter to indicate whether returning a whole device is
   acceptable, or whether a partition is mandatory.
d) Make error-checking of the user's device-/partition-specification
   more complete. In particular, if strtoul() doesn't convert all
   characters, it's an error rather than just ignored.

The resultant device/partition returned by the function will be as
follows, based on whether the disk has a partition table (ptable) or not,
and whether the calling command allows the whole device to be returned
or not.

disk: make get_partition_info() always available to disk.c

Now that get_device_and_partition() always calls get_partition_info()
when disk.c is compiled, we must always compile the function, rather
than ifdef it away.

The implementation must be conditional based on CONFIG_CMD_* etc., since
that's what e.g. part_dos.c uses to ifdef out get_partition_info_dos();
CONFIG_DOS_PARTITION can be enabled even without those commands being
enabled.

Technically, this change is required before Rob's "disk/part: introduce
get_device_and_partition" patch. However, at least when the compiler
optimizer is turned on, it isn't required before then in practice,
since get_device_and_partition() calls get_dev(), which is stubbed out
in disk.c under exactly the same conditions that get_partition_info()
is not compiled, and hence the compiler never generates code for the
call to the missing function. However, in my later patch "disk:
get_device_and_partition() "auto" partition and cleanup", the optimizer
doesn't succeed at this, and may attempt to reference the undefined
function.

commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b

    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.
