On popular request make the display driver from T20 work on T30 as
well. Turned out to be quite straight forward. However a few notes
about some things encountered during porting: Of course the T30 device
tree was completely missing host1x as well as PWM support but it turns
out this can simply be copied from T20. The only trouble compiling the
Tegra video driver for T30 had to do with some hard-coded PWM pin
muxing for T20 which is quite ugly anyway. On T30 this gets handled by
a board specific complete pin muxing table. The older Chromium U-Boot
2011.06 which to my knowledge was the only prior attempt at enabling a
display driver for T30 for whatever reason got some clocking stuff
mixed up. Turns out at least for a single display controller T20 and
T30 can be clocked quite similar. Enjoy.

Thus, we sync with community's solution for uboot/tools/env utilities:
The current location /var/lock is considered legacy (at least by systemd).

Remove test on CONFIG_LMB_MEMORY_REGIONS introduced by commit
7c1860fce4 ("lmb: Fix lmb property's defination under struct lmb").
This code in lmb_init() is strange, because if CONFIG_LMB_USE_MAX_REGIONS
and CONFIG_LMB_MEMORY_REGIONS are not defined, the implicit #else is empty
and the required initialization is not done:
lmb->memory.max = ?
lmb->reserved.max = ?
But this setting is not possible:
- CONFIG_LMB_USE_MAX_REGIONS not defined
- CONFIG_LMB_MEMORY_REGIONS not defined
because CONFIG_LMB_MEMORY_REGIONS and CONFIG_LMB_RESERVED_REGIONS are
defined as soon as the CONFIG_LMB_USE_MAX_REGIONS is not defined.
This patch removes this impossible case #elif and I add some
explanation in lmb.h to explain why in the struct lmb {} the lmb
property is defined if CONFIG_LMB_MEMORY_REGIONS is NOT defined.
This patch also removes CONFIG_LMB_XXX dependency on CONFIG_LMB as these
defines are used in API file lmb.h and not only in library file.

To quote the author:
Block maps are a way of looking at various sources of data through the
lens of a regular block device. It lets you treat devices that are not
block devices, like RAM, as if they were. It also lets you export a
slice of an existing block device, which does not have to correspond to
a partition boundary, as a new block device.
This is primarily useful because U-Boot's filesystem drivers only
operate on block devices, so a block map lets you access filesystems
wherever they might be located.
The implementation is loosely modeled on Linux's "Device Mapper"
subsystem, see the kernel documentation [1] for more information.
The primary use-cases are to access filesystem images stored in RAM, and
within FIT images stored on disk. See doc/usage/blkmap.rst for more
details.
The architecture is pluggable, so adding other types of mappings should
be quite easy.

Add a frontend for the blkmap subsystem. In addition to the common
block device operations, this allows users to create and destroy
devices, and map in memory and slices of other block devices.
With that we support two primary use-cases:
- Being able to "distro boot" from a RAM disk. I.e., from an image
where the kernel is stored in /boot of some filesystem supported
by U-Boot.
- Accessing filesystems not located on exact partition boundaries,
e.g. when a filesystem image is wrapped in an FIT image and stored
in a disk partition.
